i questioned him on putting the sackcrete in..
When we're crossing a swale or a dip with PowerFlex posts on permanent hi-tensile electric fences, we drill one or more 1/8" hole through the post just a few inches above the point. When you drive the post in with a t-post driver the wires go down along side the post but when you try to lift the post they splay out like an earth anchor and it will take a backhoe to pull them out.
Last year we had to fence across a coulee about 80 ft drop down the sides and 40 ft across the bottom. We used the 1 5/8" x 72" PowerFlex, put a half dozen of these wire anchors through the posts and drove them 3 ft deep. That was good enough to anchor down a couple of hi-tensile wires.
In the old days we would have set at least three wood posts down there and a couple on each slope of the coulee. That would have been an all day job as it would have been all hand dug postholes in that terrain. This way the boys did it in about 30 minutes.
