I just started commuting 6 months ago, 10 miles round trip. I must say it's been an epiphany. I enjoy the excersize and the fun of getting better at it a time passes. I am 54 yrs. old and started really as way to avoid waiting for the bus. I've also lost quite a bit of weight since I started all for the good.
I started with a clunker mountain bike, and now have a Giant rapid 3, since know now that I'm sticking to it.
Moved to the Bay area of California after a lifetime in Hawaii due to girlifriend who was homesick.
Well that's it.
