In that last pic the wall is just sitting there, not attached.
I set it aside and flipped the floor over. Nailed used/salvaged high density 1" foam on with roofing nails.
Then taped a couple seams, spray foamed it and got my 8 year old daughter to put tuck over all the nails/holes.
Then I sheeted it in with some thin crappy boards that were kicking around. Should be enough to keep the critters from getting at the insulation.
Then put a couple 2x4's between the two cedar beams that the floor sits on.
Got the floor flipped back over the right way again and almost got the second wall up.
Still a couple hours of daylight left, but ambition is starting to run low.
Productive day overall tho
