We always play music on our outside speakers and so do most campers around us but no one ever plays it loud enough to bother the campers next to them until after labor day, then it changes a little. After Labor day 98% of the camping season is over for most here in Michigan so in our campground the campers left are seasonal campers. Here's were it gets cool
Most of the seasonal campers know each other and are all into sports. So if theres a game playing on the radio Tigers, Lions, U of M, or State everyone has the game on and no matter were you walk you can hear the game as you visit your fellow campers to steal beer
