If it was truly an accident then I doubt it would have ever got physical. Ive run into guys on my place and I can usually tell when its intentional. If I were you, and didnt know EXACTLY where I was standing, then id have a decent conversation with the guys until we figured it out. If some guy was 50 yards on you and screwed up a gobbling turkey then you'd be pissed also. Sounds to me like you got busted, then got loud, then got punched.
