Sadly, there are people who think that everyone else should be listening to their music on the sandbar.
We play our music loud enough that if you step away 5 ft from the boat, you will most likely not hear it.
Then there was the guy in the boat next to us a few weekends ago who dropped anchor and started blasting away. We couldn't hear our music while we were in the boat. Between songs, we heard him tell his buddy that the beauty of country music was that "you can play it loud and no one would complain."
Good grief.
