Saturday morning, a bicyclist who was trail riding with a group of friends on Big Trees Trail in Redwood Regional Park lost control and crashed, Oftedal said. The mountain bikers called for help around 10:54 a.m. The bicyclist suffered from musculoskeletal injuries and had to be rescued with the UTV. Thursday and Friday, two more incidents required Gator 21 rescues, Oftedal said. Now that the weather is nice and people are going out to the parks, these requests are happening regularly, he said. "I recommend that you get out early, stay hydrated and stay at least in pairs so someone can call for help if needed," Oftedal said.
