Don't.

Just don't.

For the sake of whoever owns your house 30+ years from now.

I pulled it up in my bedroom and upstairs sitting room (? the other upstairs room) and have sanded and painted one of the floors and still have the bedroom left to sand. My downstairs bedroom will either need new carpet (YUCK!), there will be a 4-inch step down into that room to the old hardwood, or I'll need to figure out how to installed a second layer of hardwood on the framework for the current carpet (which is level with the top of the original baseboards...and yes, the baseboards are still there. Idiot owners. Between raising the floor 4 inches and lowering the ceiling 6 inches in the dining room...that is one short room).

I have never been so happy for a shower. And beer. And ice cream. I think I earned it.
