> It would almost be worth doing the research and math to determine optimal size of wire and the tension required to keep 5800 feet of wire off the ground.
What the fence builder did was to pull the wire *over* a high point, tensioning the wire with a come-along, I'm sure. That method sort of works over shorter distances if you cut all the brush down and lift the wire at the high point to let it snap into place multiple times, gradually finding approximately the most direct line.
Over 5800 ft., and without a really good brushing job, it mostly just provided the *wrong* line to run the air hammer along, drilling the holes for the tee posts into rock.
I wouldn't rule out, though, that someone, somewhere is giving a seminar explaining that because an adjoining landowner didn't come dashing out to prevent the work with the rock drill that somehow the line was "established" in a position other than the one marked by the original stakes at either end of it. So, keep this in mind if there is a seminar in your future.
That's about what I figured based on how bad off they were.:-P
