While there are still questions about whether trick-or-treating will happen in 2020 and how neighborhoods will make it possible, there is no question Americans like their Halloween candy.Sales of Halloween candy and chocolate at grocery stores are up 17 percent over 2019 so far this season, according to the National Confectioners Association. Total sales, including online purchases, is up 13 percent year-over-year.The National Confectioners Association, NCA, represents manufacturers and suppliers of sweet treats, gum, mints and chocolates.Their research showed chocolate is driving the increase. Halloween chocolate sales are up 25 percent over 2019 so far. The NCA released data over the summer showing chocolate was the treat of choice of Americans during the pandemic, with sales increasing five percent March through August over the same time period in 2019. Sales of premium chocolate during that time was up 12 percent year-over-year. Ferrara Candy, which makes Sweetarts, Nerds, Brach’s Candy Corn, Gobstoppers and more, said Halloween sales bring in about .5 billion in sales. In an interview with Axios, CEO Todd Siwak said their company learned a lot from the drop in sales for Easter. This was also the time many stores were closing because of lockdowns to stop the spread of the coronavirus. Even as shopping has picked up a little, they have made some changes.“As the frequency in-store is reduced by the shopper, so fewer trips but bigger baskets, we wanted to make sure we were there presenting the opportunity to consumers,” Siwak said. He added Ferrara Candy created more individually-wrapped confections and got product to stores earlier to extend the selling season.There are still about three weeks until Halloween, and the industry expects sales to increase. Siwak says about 60 percent of the sales for Halloween candy happen in the last few weeks before the holiday.The NCA data also suggested Americans are getting more excited for Halloween in 2020. They found 80 percent believe they will find creative and safe ways to celebrate this year. The response was just 63 percent in July. 2125

While kids are on summer break, districts across the country are working to determine whether or not to reopen schools, and how to do it safely.School leaders are racing the clock to figure out what the next school year will look like.“We’ve been looking at how can we provide a high quality education in this environment,” said Lisa Yates, Superintendent at Buena Vista School District.For Yates, that decision is simple.“We’re hearing that from families, we’re hearing that from students, we want to be back in school,” she said.At Buena Vista Middle and High School in the Colorado mountains, summer school is in session at their brand new, still under construction, building. Students and teachers are piloting a new platform that leaders hope will help come fall.The platform was installed in early June and created by tech company Wolk. It works like this -- first, gateways are installed in classroom ceilings.“The system is called Open,” said Rene Otto, Solutions Architect for Wolk.com.Next, students and teachers put on a wearable device at the beginning of the school day. “They’re given these safety cards or wristbands, so what these do is they act as beacons,” she explained.The devices currently use Bluetooth to communicate. Using the gateways, the software shows when a beacon comes within a certain amount of space of another beacon, for how long, and if the beacon moves rooms.“The point of it was to help people understand where they are in a physical space, so we can figure out if safe social distancing is being practiced,” Otto said.The school district’s technology coordinator, Matt Brooker, helped install the system. “If we did have an incident where a kid is positive, could we do contact tracing with this?” he said.For students, the idea seems simple enough.“It’s going to record where you walk and how close you get to other people,” 6th grade Aidan explained. “It’s like wearing a little necklace. It doesn’t really bother me that much.” Others weren’t as convinced. “Personally, I don’t know if a lot of people are going to want to wear them,” 10th grader Taylor said.With every tracking device comes concerns over data and privacy.“It took me a little bit,” said Reba Jackson, a teacher at the school. “I’m a little paranoid about tracking things.”“I went from feeling like it might be a little bit invasive,” teacher Robin Fritsch, explained. “It’s not a big deal. If it gives us valuable data, I’m in.”Otto said not to worry.“We really want to make sure privacy is protected. So the way it works is, only the administrators of the schools have access to the identifying information,” she explained. In other words, each tracker has a number as the identifying name. Only school admin members are able to match that number with a student. “I don’t think any parents or people want to be tracked by a technology company generally. But if that information can help make people safer, I think it’s valuable.”Otto said for the system to work fully, they need at least 60% of students and teachers using it. This helps find hot spots that potentially need more cleaning or more attention to create a better socially distanced space.“I think it’s going to be a valuable tool,” Fritsch said.As students come back, the hope is that the system will help identify who has come into contact with someone who tested positive for COVID-19, and stop the spread there. This could mean the difference between sending 10 kids home and sending the entire school home in the event of a positive case.“Typically rural communities, as far as economic development, don’t have the resources the major metropolitan areas might have,” said Wendell Pryor, Director of Chaffee County Economic Development Corporation. “So any tool like this that aids in the threat of an outbreak and the way it might spread, I think is going to be a bonus to everybody involved.”“In person is where we want to be, so we’re putting our resources there,” Superintendent Yates said. 3979

We've all been here before, trying to back out of a crowded parking lot having a near miss or even worse, a crash. But avoiding these types of accidents is getting easier thanks to new technology. It could save lives, and money.Back in the day you'd have to turn around look out of the window and hope you didn't hit anything. But now cameras are pretty standard in most new cars. They will be mandatory in all new cars starting this spring. And it's more than just a nice thing to have, it's just one of several technologies that are really reducing crashes.The rear view camera gives you a look at things you sometimes can't see with your own eyes. It eliminates those blind spots.Then there are parking sensors. Those are those sometimes annoying beeps or vibrations in your seat that let you know when your car is getting too close to something behind it.     But what researchers found to be most helpful in preventing rear crashes is the rear automatic emergency braking system. It can detect if something is behind you while you're backing up and can automatically brake if you can't or wont stop.Together, this technology dream team is reducing back up crashes reported to police by 78 percent, according to a new study from the Insurance Institute for Highway Safety.Most rear crashes don't result in serious injuries, but you never know who or what might be behind you. Using this technology could save you a lot of stress and potentially thousands in repair costs. 1503

  

With 20 electoral votes at stake, all eyes will be on Pennsylvania on Election Day. However, officials warn that counting the ballots could take days.In Bucks County, a heavily populated suburban county near Philadelphia has a population of about 628,000 people. In 2016, Hillary Clinton won the county by a narrow lead with a few thousand votes. This time around, both presidential campaigns have been courting the suburban vote, and the suburban Philadelphia counties are considered critical. Polls across the state closed at 8 p.m. EST, and now the more than 2 million mail-in ballots the state has received can now be counted. “We sent out about 200,000 ballots, which is 10 times more than we did four years ago, and we've gotten back somewhere in the area 160,000,” said Bob Harvie, Bucks County, Pennsylvania Board of Elections Chairman. “We still have mail coming in obviously today that we can accept. We had U.P.S. dropping off some ballots. We've got drop boxes that will be emptied at 8, and those will be brought here, and we don't know how much will be in those.” In Pennsylvania, more than 2 million mail-in ballots have been returned so far. The state doesn’t have a lot of experience dealing with large amounts of mail-in ballots, unlike places like Colorado, Washing, and even Florida and Arizona, where ballots have been counted as they come in. However, in Bucks County, officials didn’t begin counting ballots until after the polls closed, and a handful of Pennsylvania counties won’t start counting until tomorrow. “It's been a big challenge. It has been, you know, primarily because we were not even able toopen the envelopes until today. And there's a security envelope. So, that's two envelopes you need to open. You need to be able to make sure that everything is on there, their name, their address, the date,” said Diane Marseglia, Bucks County Board of Elections. “So, you're checking for a lot of things all at the same time and then you're pulling it out, and then, you're going to start to gather them for a vote. That's a lot of time.”If the presidential race hinges on Pennsylvania, it’s possible we won’t know who won the presidency for days.E.W. Scripps national correspondent Maya Rodriguez is in the Keystone State, bringing you the latest on Election Day. 2302
