I am but until Mr. Pence replies to my second email I can't say anything more about that. I will say this though. Meyer Broadway has a sign that states that there are no firearms allowed in that or any county park. However I don't think they have the legal authority to make such a prohibition (a prohibition that would preempt state law).
The state says that I, as a concealed license carrier can carry my pistol anywhere in the state except federal land (which may change in the near future), designated pistol free zones (of which County parks are not listed) and Private Property where the owner has posted a no firearms sign.

The way I read the Firearms and Ammunition Act 319 of 1990 a local unit of government can not write an ordinance that preempts state law. The following text is from Act 319 of 1990.

Although I haven't found the specific case I am pretty sure that this has already been tested in court and a Library in the Detroit area was ordered to remove a No Firearms sign from the premises. I'll post a link if I find it.
