I have the same problem as you man. I live near Opryland in Nashville, and I can't find anything. There might be a Go-Kart track or 2 that someone could rent out... not sure. I have heard of people doing that before though.. worth a shot.
I'm in east nashville about to start building an x22 I purchased. It's in real shabby shape, but I should have it running by the time it warms up. Please let me know if something get's organized. If I can't go on my x22 I'll roll on my scooter.
