Can you shoot a bb gun here if you put some targets like some bottles cans or anything like that??

NO! https://www.montcopa.org/DocumentCenter/View/17536/PTHS-Rules-and-Regulations-2017_DC?bidId=

No guns of any sort. There are walking and biking paths, picnic areas, pavilions, bird watching blinds, etc.

Every year or so they have a deer hunting session, but other than that, no guns

Probably not

No

I would say definitely not but you can contact the Anglers club and ask them or the park Rangers
