I raace my car, occasionally drag racing or open track days or time trials but I freakin' LIVE for autocross (SCCA Solo), it's a neverending challenge and impossible pursuit of perfection thing I guess, lol. Add to that pretty much anything car related, shows, wrenching, custom audio. Been a 'car guy' since I was 4 years old, lol.
We have a lot of fun on the kink side, and frankly between the time spent at home and the time spent in clubs and on forums, etc, that counts as a hobby.
High end audio. Reading. Scrabble. Video Poker, though not so much anymore. More, I'm sure, but that's enough, lol.
