I was commuting 5 miles each way till I got sick of it a little over 2 years ago. Now I'm retired (early, age 60) and need to start riding again! So that's on my agenda for tomorrow morning, March 23. I don't have a car, and when I commuted I did it in all weather, including downpours and sub-zero. I use both mtn bike and road bike and have no real preference, except that the mtn bike deals with the rough streets a little better.
