We spent the long weekend at my Dad's in Northeastern Lower Michigan. His 80 acres backs up to 9,000 acres of National Forest. Unfortunately, my Trailblazer wasn't up to the trip due to a lower ball joint issue, so we took our other car up, and used my Dad's 2008 TB for some exploring. It recently had an altercation with a Dead End sign, so ignore the front end damage.
The trails were extremely dry and sandy. I did need 4WD in a few spots. I think in mine with wider tires and the G80, I would have made it through if I'd aired down. It was fun none the less.
