I guess Florida's rock should be a grain of sand. It still amuses me that I have to purchase rocks down here for rock gardens, etc. Back in central NY, I'd take a drive in the country and find all I needed.

Texas has a state rock. Petrified Palmwood. I wonder why it isn't on the list? Maybe it isn't "official"?
