I'm curious as to why you would be so opposed to an electric fence. It won't do any permanent damage. It would just be incredibly difficult, if not impossible, to hold on to. I remember getting into electric fences when I was younger. I guarantee you will let loose of it quickly.

A barbed wire fence, on the other hand, can cause permanent damage. I had surgery on a finger to repair a cut ligament and part of that finger is still numb to this day.
