IT'S DONE!!!
All done. *pats the beautiful new fence* 3500 square feet of fence between me and the neighbors. All 7' tall and 50' wide of it. So tall! So beautiful! Only six hours!
I was afraid that having the fence grow by almost two feet would make the yard feel dwarfed and squashed. But noooo, it actually feels bigger now!
There will be pictures later. There may even be a "see my lovely new fence!" party forthcoming.
