Sdsester,
Wow, what a great point to bring up (and one of the reasons that I so appreciate this community of help). Thanks! I will investigate that possibility more before I do anything else. Arizona Government is in their own little world anyhow, so maybe I shouldn't be surprised if there is a bureaucratic hurdle to jump or dodge.
I guess that I also need to talk to a geologist, as all the masons that I have chatted with only have experience with manufactured brick/stone. There has to be a true "old school" craftsman around here somewhere.
Peace,
Dr. Z.
