Here in Washington theres lots of people like that espesially(spelling) on our rivers. Like this one time i was out fishing way up stream of these fly fisherman salmon snaggers and they left. 45 minutes later i had moved down stream and was catching fish legally (not snagging) and they came back and started yellin and hollerin that i had took there spot when they had left and went clear to town. So i Know what your talking about. The favorite game of bank fishermen here is to try hit the jet boat going up stream with there 3oz sinkers.Its pretty funny too.
