John,
 
Here are some pictures taken on a qalat (large adobe fortress) in Gardez, Afghanistan. I put this stone inside of what was apparently a vent on the bottom of one of the ramparts.  Hope things are going well in Eastern Europe.  I'll send you another picture when I go back through Kyrgystan.
Here is a picture (60) of the actual rampart in which I placed the stone behind me. Image 54 is the qalat where Alexander the Great supposedly once stayed. Image number 57 is me with a local policeman that we had just trained on supply requisition procedures.
