Indeed. Every summer in Michigan units from Ohio, Kentucky and Indiana are seen convoying up I-75 to train at Camp Grayling in the Northern Lower Peninsula. There are 100s of miles of unimproved roads all over a dozen or more counties that are not maintained by the county that we have always called 'tank trails'. Because of the geology of the region these trails are deep mostly hard packed sand called Kalkaska sand (this is actually Michigans 'State soil' like you would have a State bird). There are also live fire zones and bomber ranges.

Couple of interesting anecdotes about this area. Growing up my dad owned 3 acres on the Au Sable River outside Grayling. One afternoon we took his Bronco out 4 wheeling on the tank trails when a NG helo landed just in front of us. They told us to leave the area immediately as they would be commencing live fire exercises. The Helo took off but we were stuck in the sand. We frantically undug ourselves. Never heard a shot fired while we were there.

Later in my 20s dad had given me the property and I sold it and used the proceeds to buy 20 acres about 15 miles north near Waters, Michigan. One night while me and my buddies were up there for the trout opener the NG had a training exercise and we could hear the artillery and machine gun fire all night long. We felt the shocks from bombs being dropped by NG planes. It is something I had never heard before or since but it is burned in my memory for eternity.
