Okay, my better half has just reminded me of a time almost 20 years ago I brought outside my portable player. I'm an avid collector of Doo Wop music and played it just loud enough for me sitting in my chair next to the table to hear it. I had one camper behind me and nobody across or in front of me. The guy behind me was walking past us towards the office when he stopped and asked if the song playing was really "Heart of Soul" by The Harptones. It was and I apologized if it was disturbing him. He said it wasn't and asked if he could bring a chair over after he returned and sit and listen. I told him of course. When he came back 15 minutes later he brought about 7 others, including the park owner/manager. Long story short the rec room was unavailable that night but free the next. We held a 3 hr Doo Wop party the next night and it was terrific. I haven't done that again because it could easily have gone the other way.
