Moderators- feel free to move this to the commuter section if you want, I see now that there is a good commuter section here. My mistake.

nemo- actually my commute will be on a mountain bike. I live next to a lake, and my new office will be across the lake and about 2 miles by water. By single track/ trail road/ paved road it is about 4 miles (that is if I don't take a detour and ride down some river trails on the way ). By normal driving it is 17 miles. Right now I'm trying to figure out how I can go a day or two by bike, and a day or two by kayak. Sweet!
