Although they're probably done for the season, there is a nice little practice track in Vassar, MI that charges 15 bucks for the big bikes, 10 bucks for 85 and under. It's called SandBox. It's safe, it's fun, and there's some good safe sections to practice out there without risking injury to the vitals! LOL If this snow ever lets go before Dec. (fingers crossed!) they may do another practice. They don't have a website, but you can call Todd Hoeldtke at 586-909-3504. Happy trails!
