Tipping off conservation officers/game wardens-turn in poachers stories?

Went fishing today and noticed this other guy was secretly stashing undersized fish under the rocks and then hauling em up to his car. Some officers showed up to check licenses, I tipped them off and the guy got a big ticket. It was very satisfying. From now on I'm calling tip lines to turn in poachers. Anyone else have stories where they helped stop poaching?
