Been there. Lots of guards with SERIOUS weapons. One very long, isolated road in and out. I was always glad to leave.
“Lots of guards with SERIOUS weapons.”
And not just behind the wire, either. Equally serious when transporting components to/from Oak Ridge TN. I used to see the transport convoys passing through OKC on I-40. Easy to spot when you knew what to look for. The communications support vehicle was the giveaway.
Did you feel 'dread' like something bad would happen? That might be intentional...adds a layer of security. How did you feel?
