The U.P. of Michigan has thousands of miles of offroad trails and backcountry 2 tracks that you can even get your TC on your truck down. Some will require taking the TC off too as the trees are to close together or too low if that interests you. Many are marked trails/roads and unimproved but have bridges over the streams and you also can buy a Michigan Gazette by DeLorme for detail so you don't get lost hopefully. We have them for most of the lower 48 states and Alaska too. Be sure to take a good compass and a GPS too. Some back roads and 2 tracks are over 50 miles long and cross many others along the way. It's almost like a maze of way to go. Gobs of CG's all over the UP right at the offroading expanses too.
