Thanks for the pic!

I worked there in the early 70's and it is still hard to describe to people.

A half-acre footprint seems about right but the buildings are three-stories high so it seemed bigger.

The quarter-mile tunnel to get in also makes it seem much larger.

They also have a "lake" for a water supply.

Thanks for sharing your first hand experience with the place, seems like a very interesting place to work.
