Love it! Very appropriate. I suspect that many of the wineries in the Napa area suffered great loss of inventory!
I'm not sure this works. I wonder how that rock facia will hold up in a quake?
Oh, absolutely, but that could have been avoided by utilizing a storage system like this one developed at my university: http://www.ksby.com/news/cal-poly-professor-s-creation-getting-attention-following-earthquake/
The rock facia would suffer loss but given the size of stones and layout of the facility I doubt there would be many or any serious injuries.
