Just found this on the Eaton county parks rules and regulations:
19.1No person shall, at any time bring on Commission property, have in his possession, discharge, or set off anywhere upon said properties, a revolver, pistol, shotgun, rifle, firearm, bow, or other weapon that discharges projectiles either by air, explosive substance, or any other force. Provided, however, that this section shall not apply to any deputy sheriff, police officer, park ranger, or other duly appointed law enforcement officer while carrying out the duties and responsibilities of their position.
Sent them an email notify them that it was unlawful due to preemption. I'll update when I get a response.
Just received this from The Eaton County Parks Commission:
Dear Mr. XXXX
Thank you for the recent email concerning the Eaton County Parks
Commissions Rules and Regulations, and more specifically the need to
amend 19.1 to reflect changes that have been made at the State level.
We are currently working on an amendment to regulation 19.1 that should
ensure our compliance with State Law. The amendment should be acted upon
within the next couple months pending all the proper approvals and
public notifications as outlined by State Statue for amending County
Parks Commissions rules and regulations.
Please contact me at any time, if you have additional concerns or
questions regarding this matter or any other County Park related issue.
Dan Patton, Director
Eaton County Parks
