Well... I don't really know. Apparently they're all "scarred up"... how's that? they're rocks... and granite at that. Big broken up hunks of granite. The inside looks like the outside.
We'll see. The real bummer is, though, that they think they'll be able to start on Tuesday, and take "a couple of days". I'm gonna be in SFran Tues-Fri. I'll probably miss the whole thing.
If you ever find out the difference between "good rocks" and "bad rocks", please let me know. It's one of those vital subjects I have always taken for granite.
