I gnawed a hole in the floor to put a gas line through. I drilled a lot of holes real close together, and then drilled them bigger. Thanks, Rusty, for lending me the drill!
My wife found this cheap little cutter, and we've used one for the rubber roof, and this one made quick work of the re-reused billboard tarp -- trimming the excess.
Finished the bathroom, and put up a tarp on the ceiling as a vapor barrier. We had gotten this tarp a long time ago, to cover up our house while it was being built, and now I'm able to reuse it as a vapor barrier.
I came out to work on the house, and there was a just-hatched butterfly on the corner of the storage unit. It's wings are still soft. Well, I'm off to spray some foam under the house. I'll be happy to get out of the chrysilis of a tyvek suit! Time to go get that on, and see if I transform into a butterfly!
