Now, I normally don't mind crowds (you can't if you fish public water in Colorado). In fact, I kind of see it as a game... "try to catch the fish where the other person missed." But in this case, I thought the guy was being a jackass, so I (politely) said, "There's a lot of open water here, why doesn't one of us go one way or another." And he said, "It doesn't matter. I'm on the other side of the river!" Soon thereafter, he told me exactly where I could go.
