That sounds like a typical weekend during gun season in PA to me.[:'(] Seriously do what you can to get the GCOs involved and let them handle it. I understand you have an agreement to keep trespassers out with the landowner, but when it gets physical your obligation is over its bounds. Helping that landowner out won't help you if you get hurt or worse.

It sounds like you've got a bunch of bad eggs to contend with. Good luck sorting it out with the law enforcement and be careful.
