The problem I had was that I knew in about an hour or so, the area was gonna be good. Thankfully they left before it got good. We caught 9 reds, 5 were over. I did not want to give that info freely and would have motored around to make sure they did not get it by horning in on us.
BBB, I am much more pushy about duck hunting, but that is a safety issue as well. too close means dangerous. In the very rare cases where someone refuses to leave, I let them know my shell count and that we will fire one off every 10-15 seconds, ensuring both our days are ruined. Been called ugly names, but have always helped them see the light!
I reckon it pizzes me off because the week before we saw a kayaker and decided if he got within shouting distance, we were gonna invite him over to share the fish. We are not hogs, but I think one should give at least as much respect as the expect. The kayaker stayed too far away. I am pretty generous with my spots (I invited some Georgia oddball to a wood duck hunt once

and that was fun), but offering them is a lot different than having them taken.
Ducks, turkeys, flats fishing. Who has time for golf?
