I just looked at the park rules which they have posted here:
The following is a clear violation of ORC 9.68.
§ 92.07 POSSESSION IN PARK PROHIBITED.
No person, except law enforcement officers, shall carry, discharge or possess any firearms of any
description, air or gas gun, or any other missile or projectile throwing device or the ammunition
thereof within the park without the express written consent of the Director. (Reg. 3.1) Penalty,
see § 10.99
