Flying from TUL to DFW I noticed a complex of white buildings/structures just S/W of McAlestar. Looks like it sits on about 10K acres or so. White buildings spaced apart. Closest thing I can thing of is it looks like an ammo depot for the military. But those typically blend in much better than these. What is the story with them? Any ideas? If not sure what I'm talking about do a google earth search and it show plain as day. Thanks
