Fox Valley is alot of fun for about 5 hours of riding. If you like a technical motocross track, this place has a grea one. It has alot of great hills to climb, but it gets a little slippery when wet. The owners name is Wardy and here is his email address. Just send him an email and he always replies. He will probably send you some information and put you on his monthly mailing list. He runs alot of harescramble races on that property.

Good luck, and maybe we can hook up there sometime. I take my son there at least once a month.
