An update...after two months of time flying by

I have been very busy working on fence related projects in addition to "normal" everyday life stuff.
---Had to do some related projects prior to beginning the fence itself. New outdoor water spigot and electrical outlet. Will need them for the project, didn't have them.
---The original new 21' fence project has now expanded. Upon inspection of a portion of the existing fence near the new project, I found a 35' section to be on its last legs, one of posts literally rotted through completely and being help up by what was left of the rails. Also a couple smaller individual parts of yet other sections that were crying out for some attention.
--- But the biggest problem has been pressure treated lumber warping and splitting. I spend a lot of time picking only the best looking boards. Ten days later those nice boards are warped, twisted, and splitting. I have wasted a lot of both time and energy choosing, transporting, re-transporting...then going through the cycle again
I believe the lumber issues are happening because it is too wet. When I first looked for treated lumber in late summer at Lowes, the racks were practically bare. Demand is/was high because of people sitting home during the Covid crisis. So the mills rush it to the retail sellers, and it gets grabbed up almost immediately. A lot of what I bought was so moist that I could feel it with my hand. I later verified my suspicions with a moisture meter...some of the wetter pieces were in the 40% range. Old wood is under 10% by comparison. A few of the treated pieces I have brought home are more reasonable at around 15% give or take, but not nearly enough to do the project, and those good boards are 10' rails, not posts.
