Started semi-serious autocrossing with SCCA in 1970. Was severely limited by Air Force three striper pay. TR-4A, Austin Cooper S and a '66 Lotus Elan (man, I wish I still had them!)
Mid '80's I did a lot of off-road hill climbs. Had an old V6 Jeep that I had fully prepared. It could darn near climb walls. I used to enter the V8 paddle classes on street tires. PO'd a lot of people!
Tons of trophies, all worthless and they saw the dumpster years ago.
Early '90's I got back into SCCA autocross. Won two state championships. Another waste of time.
My current build is my first attempt at an all out, purpose built race machine. It may be small but it's being done right (for once). It's ironic that I'm building such a small bike after being inspired by a bumper sticker that read "Go
big - or go home"
