David Roberts participated in his first Sierra Club outing on a Yosemite service trip in 1969. Since 1977, he has led or co-led private backpacking trips and began leading for Sierra Club Outings in the Sierra Nevada and southwest canyons in 2001. He delights in the solitude and stillness of remote lake basins far from civilization. Pastimes include photography and playing Hawaiian slack key guitar and with the Santa Cruz Guitar Ensemble. To stay in shape, nearly every day he accompanies the family dog on a hike along the trails adjacent to his home in the Santa Cruz mountains.
