Bay Area filmmaker Tal Skloot will present his film portrait of Bob Coomber, who will join him for discussion.

4 Wheel Bob follows Coomber, an intrepid adventurer who sets out to be the first wheelchair hiker to cross the 11,845-foot Kearsarge Pass in the Sierra Nevada.

Bob had grown up in Piedmont in a family of avid backpackers and, while hiking in his early 20s, shattered his leg in a struggle related to juvenile diabetes and subsequent osteoporosis. After a period of depression, Bob adopted a philosophy of “no excuses” and, confined to his wheelchair, took increasingly strenuous hikes, using only his arms to get around.
