2 locations in MN that are close to I-90 on the map, Chatfield and Elm Creek. Here is a link to the map
http://www.dnr.state.mn.us/ohv/map.html I am not sure what you would need to ride in MN. The Rhino is a class 2 ATV here. If you study the DNR site you should be able to find the registration requirements. Wisconsin does not accept the side by sides statewide so no riding there for ya. South Dakota is open in the Black Hills so you probably want to ride there. Many of miles to ride there. Here is a link to look at that may help you. http://atving.us/blackhills.html Good luck and have fun.
