What can you do?
Some people are just ****ing stupid and can't make the connection between their stomping around in the water and the fish they are trying to catch.
Whenever I see some asshat do something phenomenally stupid like let his dog jump in the water in-between bank-fishermen and my blood starts to boil, I try to calm myself with the mantra, "This is public land and everybody has a right to be here - even if they're a shithead.".
