I unfortunately ran into them last Wednesday (Concourse E). They're being used as primary. Of course, I was chosen while waiting to go through the WTMD. Opted out (the TSOs seemed shocked) and took the patdown, which was so thorough I thought about asking for a cigarette afterwards.

I was not given the option to take my posessions along with me. Luckily my wife was there to pick up everything (of course, that left her to deal with our 14 month old along with all the stuff, by herself).
