Ahh, I would love to check them out.
I'm a native of Kentucky and have only lived here for three years (moved up to marry my wife). In all my research about where to wheel in Michigan it looks like there's basically nothing down here, and there are gradually more and more trails the farther North you go, until you hit the UP which is like the jackpot.
Besides being newish to Michigan I also recently got my first Jeep. It needed a new transmission and the transmission shop just finished rebuilding it. But it's down in Kentucky at my parents' place and I don't plan on bringing it up until they're done salting the roads.
So I guess what I'm saying is: I'm really looking forward to seeing the Upper Peninsula for the first time, hopefully with my wife in a Jeep during warmer weather
