Surprising discovery

I've been considering getting new flooring for my bedroom for quite some time, so tonight I pulled up a section of the carpet to see what was there. I was expecting particleboard, which is the subflooring for the living room and dining room.

Imagine my shock when I saw *hardwood* staring at me. I have no idea what condition it's in, but hardwood!

Guess who's going to be pulling up the carpet at some point this fall/winter and removing the tack strips?
