I'm so excited that my heart is racing!!!
They just cut the holes in the dining room floor for the vents, and the wood floors are still under there!!
The previous owners had told us that there was nothing but plywood under this grossly nasty carpet.
Now, here's the kicker: There had been a fire in this room, back when it was a kitchen. So there's a good chance that the wood floor is damaged, perhaps significantly to the point of being unusable.
But just the fact that it's THERE and that it could potentially be useable makes me seriously happy.
As soon as the HVAC install is done and I can wheedle permission out of Von, I'm tearing this nasty carpet up and seeing what's there. I figure worst case I'll re-cover again with plywood, but I can definitely hope for something usable.
