Fifty years ago we used to go shooting in the upper desert region of SoCal. During WWII the Army & Navy used this area for weapons practice.
I still remember walking through a dry river bed that was just completely littered with spent bullets and artillery rounds. The rains would come now and then, revealing the spent rounds in the sides of the river bank. We left it all lay. I had no desire in collecting unexploded ordnance.
As a result of the SALT treaty the Dixon pulled into Seal Beach ammo depot to offload some ordnance. I never witnessed such a security clampdown 'til that day. The whole evolution went from sunrise to sunset. One at a time, a warhead was offloaded from the ship then transferred into a weapons magazine under heavily armed guard. Eventually, we offloaded 95 nukes. Enough to light up the whole left coast.
