That’s a fence!!! Is that the I Hate My Neighbours version?
Musta cost a Corolla’s worth of cash too. A good used one at least.
When we redid our deck I was looking for 6x6 posts but the guy swore they don’t make those. So I bought 4x4s and wrapped them and made my own. I learned later the guy is just one big lazy MOFO when I asked for something else much later he said they can’t get anymore and the next day there it is, on the shelf. If you wander the lumber section now...6x6 posts up the wazoo.
