Just started in the middle of last summer.
1) Sick of buying gas for my car driving to work everyday in the summer. Picked up a crappy 80's road bike from a rummage rode that to work for about a month. Then Sheldon's site really influenced me to try fixed, saw a Pista my size on craigslist snatched it up.
2) Pista
3) Milwaukee summer, Eau Claire during school
4) Ride to work, school, fixed is fun.
