More on Mich state parks

Just for the heck of it, I looked at two other southern states (Georgia and South Carolina) and both have park passes. While I didn't see a non resident one on either page, the yearly fee is more than the non resident fee for Michigan. Georgia is $50 year or $5/day. Either way, for 8 days, the OP would pay more than at Michigan. In South Carolina, they charge $75 for a year or you can get a 7 day pass for $50. I did not see a daily fee, but I imagine they do have one. But with their higher rates, I imagine it would be at least $5 or more per day.

Again, we are lucky in North Carolina as they do not charge such a fee or have a park pass.
