I hope this is sarcastic. If not, advising someone to move because inconsiderate SUP users are putting surfers at risk is a pretty ****ed up thing to tell someone to do.
Or you could stop being pussies and call the assholes out when they do stupid stuff. The SUP hate on here is ridiculous. And if your break is so damn crowded that you can't catch a wave without someone dropping in on you, then moving is certainly a good option.
