The specs on the DPG (Desert Proving Grounds) are:
Approx. 3500 acres, 70 miles of roads....at one time was over 5000 acres....
DPG has been recent sold to a housing developer for 300 Mil, or something like that....we will be leasing back for 3 years until a new facility is finalized
You can find some cool old shots of it at this link...
