I'm rethinking the electric fence. I'm liable to electrocute myself even though I was given wonderful directions on how to do it. I'm afraid I will 1)hit one of my waterpipes, sewer lines, or buried powerlines or 2 not be able to drive the grounding poles far enough. I live on a mountain, no such thing as unrocky ground!! Anyone know where I can buy one in the USA or even better plans to make one???
