Yeah that's quite a bit more than So Cal. I've heard that it's due to the lack of aggregate in the south - that it's got to be hauled in by train.

Looks like a good job you've got going there. I see some felt, so I am assuming those garage slabs will be isolated from the house slabs, so that's great!

Finally, have you considered having the concrete polished? It produces a wonderful finished project, with nothing to fail. Most epoxy's are pretty good nowadays, but all are tested in heat, humidity and the presence of hot rubber tires pressing down upon them for hours on end.
