I just stumbled across an AG opinion you might find interesting:
http://www.ag.state.mi.us/opinion/datafiles/2000s/op10198.htmApparently were not allowed to carry in state parks unless we have a hunting license, and only during firearm season, unless it's unloaded.
A person licensed to carry a concealed pistol may possess a pistol while hiking or camping within a state park provided that the pistol is not loaded. A person licensed to carry a concealed pistol may possess a loaded pistol within a state park only during established hunting seasons on lands designated open to hunting or at a target range established by the Department of Natural Resources or during an officially sanctioned field trial.
A person licensed to carry a concealed pistol is subject to the rules, regulations, and orders of the Department of Natural Resources regulating the possession of firearms and may not possess or carry a pistol while hunting deer during "bow and arrow only" hunting season, unless the person is licensed to hunt deer with a firearm and is hunting in an area open to firearm deer hunting.
I thought Mike Cox was smarter than that, apparently not.....
