The original (sabotaged) wood floor

It's a sad day in house restoration history (okay, maybe it's just a sad day for me). Matt sent me a photo of the floors today after removing the sub floor from on top. I can't believe someone would neglect and ruin a beautiful hardwood floor this way. He says there are about 30 nail holes from each piece of plywood and on every plank. Add to that the glue, paint and god knows whatever else that's on there and there isn't much hope.

We are kind of past the point of no return on this. I did ask again if we could salvage it, but there is some decent sagging in some areas and with all the damage from the nails, we don't know how it would turn out if we had someone attempt to refinish it. Spending the $ to take the chance on *if* they'd even come out decent, not to mention the 20% restocking fee we'd lose on all the new hardwood we have piled up in the next room ready to go and it's just not feasible. But, really, someone should be ashamed for doing such a thing.

What I do wonder about is why the upstairs floors are a light pine and the downstairs floors are so dark? Strange.
