Not to much that is legal. I try to stay away from that. There is a large spot near 470 and Raytown Rd, but I've heard it's owned by Flatlanders Heep Club. A friend is trying to follow up on that. I live in Olathe and there are some stuff out by Hillsdale. Very small though (mostly mud) and probable not worth your drive. We go to Tuttle Creek 3-4 times a year. Let me know if you want to head out to Hillsdale, we go out there 1-2 times a week, mainly because it's the only the near-by. I've havn't had the truck recently, the 12 bolt is dying, and I need money for new wheels before the 14 bolt goes in.
