Baldwin area in Lake County. Very ATV friendly with plenty of ORV/ATV trails. Only down side is the trails aren't very difficult. But I've found the faster you go the funner it is there. ?
Sounds like most of the wis state trails when dry. When wet its like miles of mudding. How r traols in u.p? Considering riding up to u.p through northern wis atv trails.
Best trail experience on Michigan is Drummond Island. You get there by ferry from east tip of the UP. Rocky, technical, spectacular views all along the shoreline.
