Been in a couple of situations with a duck hunting friend a few years back the worst one involved some local law enforcement folks . Two islands fairly close in the back of Mud Creek . We got there early , put our decoys out , hung a light to let everyone know we were there . About 15 minutes before shooting time a boat approaches headed for the other island . My hunting partner has a pretty good temper and doesn’t care to get loud . Guys pull in directly across from us and start setting up . My bud yells at them we were here first , their reply : we always hunt here and we are sheriff’s deputies. Of course his reply was I don’t care who you are you are a bunch of horses butts . Eventually we move to the other side of the island . No shots fired, at each other or at a duck .
