The good news: I can pass my front hallway again. I cleared a
chunk of the dining room floor, slid the plywood out of the hall
and put it in the floor so that it bows up in the middle, then
stacked the stuff that had been on the floor onto the plywood
hoping that the weight would flatten the wood a little over time.
I even stuck my big bass amp there (it should go upstairs to the
music room, but until I need it there, it's serving as a weight.
That did not press the wood flat. Oops. I could do it with
boxes of books from the basement, but that seems too much trouble
at the moment. (Doh! The two boxes of LPs are near there and
could be moved onto the plywood easily. I'll do that later.)
Even if this doesn't de-warp the plywood, until I get my house
organized enough to be ready to use the dining room as a dining
room, the plywood is less in my way under a pile of stuff than
blocking the hall. I just need to make sure I don't render it
too difficult to extract between now and next Pennsic.
The bad news: Ow! This was pobably not
the best day to do that painwise, but I had a burst of energy
and was really frustrated at the obstruction. Ow.
