Looking at this website brought back a memory of what probably was this ride from probably the late 80s--could that be? I recall going with a friend who was a serious rider, and I had my--this is the truth--my old very non fancy "girl's" bike. I was of course younger then, so I managed the first 40 miles (up to lunch) with just sheer strength from winter tele skiing and hiking in the Sierra. I recall that it was really beautiful, especially early the morning, going past the wineries and all of the flowers.
The bicycle is the most civilized conveyance known to man. Other forms of transport grow daily more nightmarish. Only the bicycle remains pure in heart. ~Iris Murdoch, The Red and the Green
