I have had this happen as well. Guy stopped mowing his lawn and came and told us to leave. The funny thing is it was his neighbors dock, there was no boat in it and we were casting into the empty slip. He said "come on guys, you know better than that" I asked him what he was talking about and kept fishing, I never get out of the boat on to someones dock, dont tie up, etc.. I know some guys have had chips on their boats from people casting close and would understand that would piss someone off. Not the case where we fish. I am sure the crappie have been caught from this dock for years. There are 1960's style seats mounted around the dock.
