Junkman, there is a track on the south end of St.Joe, Knobbyhillmx.com should get you there for track info. If you travel on down to KC there a few mx track facilities to choose from. You might want to check Mostatemx.com for more mx info.
Junkman, they use to have a track in Sparta, but it was about like riding at Chadwick, only with jumps ;) . They do have a brand new track just North of Sparta about 20 miles called Spring Valley Motocross. Don't know if that's what you are talking about. But we have about 5 or so tracks around Spartas general location. Let us know if you can't find what your after.
hey thanks guys! The reason being is my "Team" likes to take a trip to some other track or OHV park every year and try different stuff (ex. dunes at little sahara) I hesitate to tell you that some of my "Team" members are sport quad riders, We just like to be diversified in riding terrain and abilities.
BTW I ride a KDX250, KX250, GAS GAS JTX270, as well as vintage street and dirt bikes. Just so you know I am a motorcyclist and NOT a (scum of the earth quad rider), although some of my friends are.
