The recently-completed fence in the Gunnerson backyard. The fence is 4'1" high and runs about 80 feet across the yard.
The wide boards are 5.5" wide, and the thin ones are 2" wide. Posts are embedded in concrete 18" deep, all the framework is pressure-treated, the cross-rails are attached with Simpson Z-max angles, and the boards themselves are attached with stainless steel fence nails (so the boards don't stain).
Total cost - somewhere around $1000.
Total time - longer than I had hoped - especially since all the thin boards had to be ripped.
