Santa Rosa’s Randy Harlan and Bolinas’ Garnett Silver-Hall are known for using wheelchairs the same way others use skateboards-- grinding on rails and riding off ramps. The duo are both adaptive athletes in the "chair skating" community and founders of Northern California's Wheelchair Motor Cross-- WCMX. After connecting through mutual friends, the two have skated at parks in Northern California and competed in Southern California. Now Randy and Garnett teach other folks how to become involved in adaptive sports. This week we hear how it feels to drop into a bowl at the skatepark and the dangers of attempting a backflip in a wheelchair.
