Frontsight!,
Hey, do you get to ride in a bus after going through the security building? If it's not the same place, I worked in one just like it about 10 years ago.
Something to think about, that I always kept in the back of my mind while working there. Those 18 to 20 year old "guards" have/give no lee-way in their enforcement of their orders. I saw them hold a full bird colonel against the wall because his new badge (everyone was being issued new badges) wasn't correct. And as I pointed out to one of my gun-ignorant co-workers when he was a little un-happy being detained in a hallway for a badge check - "them guns they got can shoot 30 software engineers a second (M-16)".
Just scout a safe way to and from this place, and minimize trips on the way home after work on the day(s) you have to go there. Don't take the risk of carrying there, either in your car or on your person. If you do get ready to say hi to Tim or John (McVeigh or Gotti) that is!!
