I'm a little more aggressive in these situations, soon as some yahoo starts coming toward our boat or even when I've been on the bank and ketchn I put on a heavier jig and start casting right at said intruder. if they keep coming will put it on their boat at them and say Oh sorry but your stupid intrusion into where I have been casting is YOUR fault. they usually get the hint.

then there is Mark Twain, where folks don't have any common sense nor take hints too well. you get crowded quite a bit during the spawn so we are more likely to take a position on the bank and toss rocks at any intruders.
