BTW, here's a story on how smart a hog can be: Fellow had an electric fence hooked up straight to 110 volts. Hogs were still tearing up his garden, so he sat up to watch how. There was a slight downward slope leading to the garden, and at dark-thirty here came the small herd at a run. They knew the wire was hot, but it was worth it to slide under with the wire rubbing them all the way, then get up, shake and start eating. He neglected to carry a gun, so continued to observe them get a running start at departure time, only to run/slide under the fence again. Stubborn critters. Steve
