My first overnight camping tour ride was from my place in San Francisco to China Camp State Park back in 1998. It's 35-40 miles one way, IIRC. Was riding the Rivendell Atlantis I built up from a bare frame. Had Arkel panniers front and rear, Vaude handlebar bag, and the rig weighed 93lbs fully loaded. What a pig, but could it ever fly downhill!
