I heard of one instance in which kids were hanging around in the parking lot of a convenience store, harassing customers and making nuisances of themselves, till the proprietor got the idea of playing classical music and opera over a small PA system.

Solved the problem almost immediately.

Sorry, can't remember specifics of where the incident occurred.

When The Yorkshire Tornado and I first moved into the house we're in now, they guy next door used to play Toronto Blue Jays games over the speakers around his pool every Saturday when YT wanted to spend quiet days working in her garden. One Saturday while I was out of town she took a boombox outside and played opera, Vera Lynn and brass bands all day at top volume. The guy next door NEVER put his ballgames on again.

Cheers,
