Communication will replace fingers - I don't know how many times I've seen it, Boaters assume that someone is trying run them down by coming close to them when all their doing is trying to give them good water. Then the arms start flailing, everyone starts screaming, fingers are flying, and everyone wants to kick everyone's ass. Just avoid the situation by slowly idling up and have a conversation about what your going to do before you do it. I've even seen fisherman be fine if you just talk to them first. I've even gone up to jet skiers and told them if the give me 20 minutes of good water I would make a wake for them to jump when I'm done riding. Tubers, that's a tough one, But you can try, offer them a beer or something. Or just give in and surf when the lake gets too busy. The point is the lake can be destroyed by 2 boats driving badly. or everyone can have a great day on the water with a little education.
