i found a few, not any right in ames that i have seen. seems like des moines has some. from what i saw they do a lot of traveling to find good places to offroad. that doesnt really fit my schedule that well at this time. i just wanna find a cool place to go drive around here. i emailed the dnr and they said that they have no public places yet. but are working on it. im gonna keep researching and ill keep u up to date. you should do the same. lets figure somthing out.
