I had a similar problem in Genesee County couple of years ago. I presented the Michigan law to the head of Genesee County parks Rangers. My the way a very nice man and pleasure to work with. He said he was aware of the law but that he does not make the laws the County Park Board does. It was brought up at the County park board by someone ( Not me). After about 6 month they rewrote all or most of the parks gun and general rules. They sent me a personal copy before it was even printed. Now it is in compliance with Michigan law.
Have your park person get in contact with Genesee County Park Ranger Cheif
I think his name is Mr. Parks ( no kidding ). If you need more information contact me.
