Great job Joe! I just finished my fence but I have 1/2 acre contained now. We have a 4’ Picket. I used the same 4x4’s, string, post level and quick dry. Then we painted it black with a sprayer. I think each 8’ section was about $40 for the pickets and I don’t even recall now how many sections lol but way over $500. My wife bought some caps on Amazon as well and we’re happy overall.
We have conservation land behind us and they don't like solid fencing that can "impede the wildlife traffic". This was the easiest and cheapest way to keep the kids safe without ruffling any feathers with the town conservation department. lol.
