A two car accident on Highway 101 just north of Alisos Canyon Road last night sent two people to the hospital, one with major injuries. The CHP says 31-year-old Keith Thompson, of Santa Cruz, drifted from the southbound lanes into the northbound lanes and hit another car driven by 56-year-old Colleen Harmon of Arroyo Grande, who was taken to the hospital with minor injuries. Thompson sustained major injuries and was airlifted by helicopter to a hospital. Santa Barbara County Fire said it took 20 minutes to get Thompson out of his car. The cause of the accident is under investigation by the CHP.
