Let me think...

1968: Schwinn Stingray with AS three speed with a super cool stick shifters. (Stolen).
1972: My dad found an early 50s 20" skip-tooth Schwinn 2that I rode in cruiser mode for a year or so, it got stripped down and put into early BMX mode (I now regret that as it was such a cool bike in original form ).
1972-77: Pat Littlejohn BMX, Webco BMX, Redline BMX.
1977-80: Highschool, too cool for bicycles...(what a dumbass).
1980-81: Sixties Schwinn 26", 1st "real bike" a local builder in Lincoln Ne. Built a Reynolds 531 Frameset, built with Shimano 600. (Stolen)
1982-84: Woodrup Giro-Tour, Mongoose Koz Kruiser 26" BMX, Lotus ???, Gitane Super Course. Sold all the bikes to go be a climbing bum in Colorado.
1985-2005: Climbing/Skiing bum. Nursing school, Army, three marriages...no bikes ;-(
2005-Now: Saw a local add for a Rivendell Bleriot that totally tugged at my heart strings, and have had a bunch of bikes, right now I have. A Woodrup Giro-Tour (again), 85 Trek 520, 86 Rock-Hopper, mid 90s Rock-Hopper.

Cheers,
