More floors

I cut, glued, and screwed down the OSB that I already had upstairs, so now when I get to the top of the stairs I actually have something to stand on.  Then I had to move more up from the garage, which was more of a pain than the last time since there was about a foot of snow on the ground.

For the bathroom I decided to use pressure treated plywood instead of the OSB because of all that water damage from before.  It cost more and was heavier, but hopefully it means I won't have to replace it for a long time.  When I put it down, I only put a few screws in each since I'll have to pull it back up for doing plumbing.

And it's all done

Now to clean up and put down the paint lines for reference
