I know that Ft. Mitchell has a city ordinance about "discharging a projectile" in the city limits. This includes paintball guns, bows, sling shots and BB guns. As well as firearms. I would assume that other places in NKY are the same city wise. I was under the assumption that the only place besides private land was Adair WMA in NKY and I think its limited to bows and muzzleloading.
don't quote me though... I've been wronk before.
