Yesterday, I looked at Google Earth to see what it was showing at the F.E.M.A Coffin sites.
The last time that I looked at them was after my brother saw the Conspiracy Theory T.V show and asked me what I could tell him more about F.E.M.A, I found out that the Coffin Site (Lat 41°31'8.76"N Lon 86°41'22.50"W) that’s located about a mile West from there underground bunkers (facility) that’s the Old Kingsbury Bunkers (41°30'20.58"N 86°36'34.79"W) that they were Whited Out. But, the ones that were located in Ga (33°33'57.36"N 83°29'6.26"W) could still be seen.
Now, the Kingsbury Site was still Whited Out but the ones in Ga were gone. You can still see the imprint of the stacks that were there.
Where did they go?
Here is an old site that can show you a little about it.
