Lets see, around here, there's paintballing, hunting (particularly the doves that sh*t on my car, which is fun when combined with paintballing, nothing more satisfying than a pink painted dove lying on the ground)
I've been skydiving- that was a blast
Open track events - those are really alot of fun, but they require alot of coin to participate in them consistantly
Drag racing at the track - fun, but some tracks are far away, and are only open on weekends
Physic's studies - okay, this one might be just me
I tutor alot in my spare time- especially hot sorority chicks with their college algebra

Working on the car, cleaning up - I do have a bit of a case of OCD[

]
Carpentry, or just fixing crap up, fixing the house up and remodeling stuff like that - ironically, even though I can't do crap mechanically,
woodworking wise I'm actually quite decent if I do say so myself
engineering crap - I'm actually working on a really cool design right now
sitting on my ass and doing nothing is a ton of fun though, and getting hammered every once and a while has it's bennifits as well
