I was talking with a customer the otherday and she told me a story of how her father created his own electric fence to keeps animals away. He stripped off the ends of some wire and stuck one end in the 120volt recptacle on the back of the garage and attached the other end to the fence. She said she grabbed hold of the fence and could not let go. Her father had to yank the wire out of the receptacle to free her.
This fence was also attached to all of his neighbors fences. I guess he decided this wasn't such a good idea after all.
