Most all the places I go are private land, that are only open a couple times a year, it sucks. heres a few: Timber ridge in Onawa Ia, been to knoxville Ia a couple times, and Manhattan kansas is really good which is open to the public. You know of any other places?
The only place I know of up there is in Knoxville, IA. The Tall Corn Cruisers have an event there very year. Its pretty small though, only a couple hundred acres.
