Driftboat or sled, it does not matter, you will not make anyone happy no matter how curteous you are. In a drift boat if you go by close you will take too much time and they think you're running them over, if you go down on the other side you are on their water. Just smile and wave and drift by, do your best and forget about making them happy.
If they throw lead, that is assault, take pictures and turn them in.
