A friend of mine wants to take his kids riding (they like to MX)during their school break mid-April. We are in Wisconsin, so he was thinking of heading south to (maybe) more reliable/warmer spring weather. Any open MX tracks or riding areas aroung St. Louis or anywhere else about the same distance? I don't MX, I'm an offroad guy, so I know some trail areas, but I don't know about the tracks. Thanks!
