I think there are 1087 in my list at present, with several in this forum thread from MossRoad that I have not gotten to yet.
I am still adding sites from LokshuppenGER's list for the Non-U.S. site list... it is rapidly approaching the U.S. list in size... I am shocked at the number of sites in some European countries! I think some far exceed the U.S. in sites per area (like there are 312 in Germany!)
I have been waylaid by the loss of my access to the on-line storage space, but that may have been resolved, so I am back working on the lists again. Still it is slow going! It is amazing how many there are/were and I am pretty certain I am no where close to how many there really have been. So many are just barely an outline on the ground in old aerial images and are now replaced by office buildings, parking lots and even plowed over farm fields (yet some of the outlines in the dirt are still discernable during certain seasons of the year).
I'll be uploading new files in a week or two. (hope hope hope!).
