A while back, during my rainy period someone asked about a long lasting fence that was dog proof and was easy to weed under. This was my answer. That's 2 7/8 oil field pipe, the concrete is 24 inchs wide, with 3 peices of #3 rebar, center one welded to the posts. Wire support at bottom is 7/8 sucker rod. 2 coats red primer, 2 coats aluminum topcoat. Commerical 6' chainlink. I figure it's the last fence i'll put up in my lifetime.
