cooperland is only open on scheduled practice days. the next one is nov. 10. last i knew, the ponca track was open every day for practice (it's the same track they run the nma nationals on). i'll see if i can find a phone number for it. we have a 500 acre riding park in stillwater that has miles of trails, a gp style track and a supercross style track. it's open everyday, $25 yearly membership. i've seen many tags from mn, ia, wi etc. there in the winter. we also have an excellent dune area open 24/7 year-round. it has camping hookups, real bathrooms, hot showers etc. i highly recommend the dunes. there are also several mx tracks with open practice.
