My mothers friend is a cop on a local lake. She said that you don't get pulled over unless you're being dumb. Even if you are driving by them with a beer in your hand they don't pull you over. She said most people let go if they're just a little drunk too because by the time they got back to shore and in to get a blood test youde have sobered up enough by then. Not saying to do it, just saying what i was directly told.
