The computer simulatiuon sounds like a great idea, though I have not yet seen 
the one for SD.   Meanwhile, reconstruction is physically impossible at 
Monterey or San Francisco, and politicaly impractical at SD, so SB will have to 
remain the only partially reconstructed presidio in California.   We have 
successfully incorporated surviving historic structures into the reconstruction and 
do thorough archaeology before any above ground building.   This is an 
alternative to the current NPS philosophy of stablizing ruins. At the same time, it 
costs the taxpayer nothing.
