there is a track in royal city that is open. it cost $20 per rider and they have a pee-wee track, a mini track, a big bike track and a supercross style track. i was just there today to check it out and was pretty impressed. the owners name is steve and i guess you call before you go out to see if he will be there. his number is at this web site, and when you call him you can get better directions than what are listed.

p.s. i only saw about 10 people there and i went on a sunday.
