+1 on wilson's and Texas Boy's replies.
I just started doing track days with NESBA and have been bitten by the bug (where do you live: here's a place to find track days near you: http://www.sportrider.com/ride/146_0308_track_day_organizations/index.html ). I've been a road rider for about 7 years now and I'm kinda done with the street riding. Don't get me wrong, I'll still ride on the streets with my boys, but I just don't appreciate them as much any more. Take a look at some of these pics from the last time I hit the track: http://picasaweb.google.com/chrispak/TrackDayPart2?authkey=11LimrTRnYo&feat=directlink
If you look at the bike, I've got the Hotbodies track body work (which is crap btw) for the cost of a single side fairing. Do the track body work and get out there! Oh yeah, if you look in the background in one or two of the pics, you'll see a guy wearing orange, he's a control rider, he's there to make sure you're never over your head. One thing about putting your knee down... one of the control riders that was out there with us told me one thing... "I always focused on getting my knee down when I first got out here... that distracted me from my primary goal... to get better at riding. When I got better and faster, my knee naturally came down, 'cause I wasn't thinking about it. Oh, yeah, btw, the 1st time you get your knee down, it's going to scare the $hit out of you"
