This got me motivated. Today I visited deneva. The last Saturday of the months the ham radio swap meet at Northrop Grumman . I grabbed my camera and went. I recreated all the camera set ups, took photos and then- during the last section - noticed a sign that said photography prohibited. Ironically the signs were located on the cafeteria of the facility. So my last few "then and now" we're a bit hasty. But it hasn't changed all that much in 45+ years. It was a lovely visit to deneva, albeit overcast.
