A lot of whiny people complaining about beach “etiquette”. The beach is not a church. It’s not a retirement home. It’s not a cemetery. It’s a place for people to unwind and have a good day by the water. It is not a place for those who seek peace and quiet. And it’s never, ever going to be anything but that. Get over it. The music and playing and having fun is not going to stop. If you want peace and quiet, stay home.
