SAN DIEGO, Calif. (KGTV) - The City of San Diego has a new challenge that promotes bike riding, exploring the community and supporting local businesses. The Better by Bike blog is website that features everything from bike routes, to bike repair tips, to features on local bike riders.Part of the new program is a scavenger hunt that takes riders through the mid-city area. It ends Aug. 30 and is a competition to see who can get the most points after visiting local businesses and answering questions. The challenges range from taking pictures of specific spots to describing murals painted by local artists. It uses the Scavify application. Winners will then be awarded prizes, including gift cards to local restaurants.Anisha Gianchandani is the Climate Advisor for the City of San Diego and said this is part of a bigger-picture project to decrease greenhouse gas emissions and make San Diego more livable.“So it’s really just a fun way to get outside safely, enjoy your neighborhood and support small local businesses,” she said, later adding that “when you slow down, you get to see so many parts of your neighborhood that you normally wouldn’t see in a car.”It also helps local businesses. Stores and restaurants had the chance to submit their locations to be part of the scavenger hunt, which brings foot traffic to the area.Juan Pablo Sanchez’s family owns Super Cocina, one of the stops on the scavenger hunt. They had a local artist paint a mural on their wall outside, and their question pertains to that art.“We want to encourage you to use these streets, to go through us, to see our culture, to see the people that live here,” said Sanchez.Rudy Vargas, a native to the City Heights area, has embraced the challenge, heading up the leaderboard. He said even though he is familiar with his home, he’s still learned new facts about his neighborhood.“It was a good way to revisit some of my favorite places in City Heights but also visit some places I didn’t even know existed,” said Vargas.Vargas said he first picked up a passion for riding bikes when commuting to SDSU as a student, and has since kept up the passion.“My hope is that we continue this culture change and we step away from our vehicles because like I said there’s no other feeling like it,” he said. 2286

SAN FRANCISCO (AP) — A firefighter who died while helping people evacuate a Northern California blaze was killed by a fire tornado that at one point reached a temperature of 2,700 degrees Fahrenheit (1,480 degrees Celsius), officials said.Redding firefighter Jeremy Stoke died after he was enveloped in seconds by a fire tornado with a diameter of 1,000 feet (300 meters) and winds up to 165 mph (265 kph), the California Department of Forestry and Fire Protection said in a report released Wednesday detailing his death and the death of a bulldozer operator.Videos released with the report show the massive blaze burning in a populated area and sending a cloud of thick smoke up into the air with flames swirling up into the sky.RELATED: Firefighter killed battling Mendocino Complex fire  The tornado ripped roofs off houses and flung power line towers, cars and a shipping container into the air near the spot where Stoke was overtaken by the flames, according to the report.Cal Fire officials said that on July 26, the 37-year-old fire inspector was driving his pickup truck down a Redding road, working on evacuating people. One minute later he radioed out a "mayday" call saying he was getting burned and needed help.Stoke "identified himself by his radio call sign, and stated that he needed a water drop and was getting burned over," the report said.When an engine captain tried to contact him shortly after, there was no response, it said."Observations from witnesses and other evidence suggest that either several fire tornadoes occurred at different locations and times, or one fire tornado formed and then periodically weakened and strengthened causing several separate damage areas," the report said.Stoke, whose remains were found the following day, was one of eight people killed since the blaze started on July 23 with a spark from a vehicle driving on a flat tire.RELATED: A flat tire started the deadly Carr Fire and days of devastation in California  The wildfire has destroyed nearly 1,100 homes. It was 71 percent contained as of Thursday.The report also detailed the death of private bulldozer operator Don Smith, 81, of Pollock Pines, who was killed when his bulldozer was caught in the flames while trying to improve a fire line, defending a home during what the officials say were "extraordinary fire weather conditions."Both deaths and the injuries occurred within an hour and 50 minutes in one 3-mile (5-kilometer) stretch.Smith was trying to improve a previously constructed a fire line near the Buckeye Water Treatment Plant outside Redding after 5 p.m. on July 26 when other firefighters noticed "a rapid increase in fire activity."It jumped the fire line and a Cal Fire crew chief said he made several radio attempts to tell Smith to "get out of there." Two firefighters in the area also "recognized the urgency of the situation" and tried to reach Smith on foot but had to turn back because of the encroaching flames.Smith reported that he was cut off by the fire and was pushing on in his 2002 John Deere open cab bulldozer in an attempt to reach a safe area. He also requested water drops and four helicopters began dropping water through the smoke and flames around Smith's last known location.Once the smoke cleared, a pilot saw that Smith's dozer had been engulfed in flames and there was no sign of the protective metallic tent that firefighters deploy as a desperate measure when they are about to be overrun by fire. After two attempts, a fire captain was able to reach the bulldozer two hours later and confirmed that Smith was dead. 3592

SAN FRANCISCO (AP) — A judge ordered California's attorney general to release police misconduct records predating Jan. 1, when new transparency legislation took effect.San Francisco Superior Court Judge Richard B. Ulmer, Jr. on Friday also rejected arguments by Attorney General Xavier Becerra that his office should not have to release records of local law enforcement.The legislation was designed to guarantee public access to disciplinary records involving investigations into officer shootings, use-of-force incidents and incidents involving officer misconduct.The tentative ruling was a win for the First Amendment Coalition and National Public Radio member KQED-FM, which sued Becerra's office for records under the legislation."Judge Ulmer's order sends the clear message that the Attorney General is not above California law," said David Snyder, the coalition's executive director.In response, Becerra's office said Friday it would release records from before 2019 but only those regarding Department of Justice officers. The office said in a statement that requiring the office to release records involving other departments "would result in duplication of efforts."The judge ordered the attorney general's office to meet with the coalition and KQED to work out the logistics of releasing records.Ulmer said the 1st District Court of Appeal had already decided that the law is retroactive. He also dismissed the argument that making the attorney general provide records of local law enforcement would be burdensome.Ulmer said lawmakers could not have been oblivious to the potential cost of carrying out the legislation, and "the people will likely be agnostic as to which tax-funded agency foots the bill." 1724

SAN FRANCISCO (AP) — A scathing grand jury report released Tuesday after a 2018 Northern California wildfire killed 85 people found that Pacific Gas & Electric officials repeatedly ignored warnings about its failing power lines, performed inadequate inspections to focus on profits and refused to learn from past catastrophes. The 92-page summary says PG&E's corporate culture elevated profits over safety and encouraged shortcuts in delivering highly dangerous power. Company CEO Bill Johnson pleaded guilty on behalf of the nation's largest utility earlier Tuesday to 84 felony counts of involuntary manslaughter. Prosecutors say they did not have enough evidence to pin one of the deaths on the San Francisco-based utility. 742
