Wait you went to a summer camp with an electrified fence? Is that common?

Very common in rural areas. Electric fences are cheap and easy to relocate.

But these are not the lethal electric fences that you see in trashy science fiction movies.

These are specially designed to put out a high voltage pulse which gives a nasty bite, but is basically harmless.

Sure I assume so, certainly ones I've been to. I mean the camp obviously wasn't using electric fences to keep the kids in, but the surrounding farmers where using electric fences to keep their cattle/horses/sheep out of the summer camp.
