Really agree with the courtesy thing. This is a recreational sport, for fun, so don't make it a life or death rudeness deal. Enjoy it and work with others in the area. Btw, the video show fish surfacing at a cove or mouth of a creek, at a point. So explore that type terrain all around the lake you you will probably see the pattern repeated where no other boats are at. Seek points near deep /channels that are the highway for schools.
