I know what the law states, but first hand experience, that's not how it works. A few years ago, we set up about a 100 yards downriver of an empty blind. The blind "owner" came out at 8 am and wasn't nice about anything. He parked his boat about 25 yards from us and shot at us a couple times as we were picking up. He did get reported to the law, from what I understood he was a known "troublemaker", but nothing was done about it.
