In northern MN, they put electric around the beehives to keep the bears out. It seems to work. Don't worry about the kids - you can either unplug the electric when they're outside, or warn them that touching the fence WILL HURT. They'll touch it anyway, and then learn their lesson. I have 3 grown DS (farm kids), all of whom touched the fence at one time or another. They're fine. Well, mostly, anyway....
