Over the years I've; commuted in SF, from Marin to SF, in Oakland, in Mammoth Lakes up to the ski area, in June Lake CA, in Squaw Valley including winter riding in the snow. Now I have a boring ride through Fremont but it beats driving.
I ride two recumbents and also have a mountain bike and a cyclecross bike. For commuting I use a Bike-E which is also used by my wife. For touring I use a Vision R45 which takes me on about 6 century's a year including the Markleville Death Ride which I've completed 6 times I participate in Critical Mass rides in SF and Berekely about 5 or 6 times a year. I have a Van which I use for camping, going skiing and shopping but almost never to work.
