Actually I had the opposite motivation. The 1st time I ever tried FG was at Hellyer Velodrome in SJ CA.
They rent Lansters for $5/all day. I like it so much that I converted my vintage Nishiki Pro over to FG. That got me to puchase a real track bike, but customized so that it would be good for long rides on public roads.(A Waterford 1700 with 2 water bottle bosses and a drilled fork and cable stops for a rear brake too.)
I am primarily a roadie but I LOVE my fixies too.
Unfortunately the closest velodrome is 4 1/2 hrs away (T-town PA) but I hear that an indoor track is being built in Valley Forge PA.
Track riding build great skills such as sprinting and pacelining w/o brakes

. The interval training is awesome and team pursuits are big fun. If you like FG you owe it to yourself to try riding on a velodrome.
BTW most tracks require you to get some training (provided by them, usually on Sun mornings) before you can take part in their regular program so there is a culture of safety and no "cowboy antics".
