That's my family and me over on the right (bearded guy with two girls). We have no idea when this was shot, and weren't aware of it at the time. My brother-in-law saw us on the show and my sister sent us the pic! She took this shot with her iPhone after freezing it on her DVR.
It's Dulles airport, but we can't figure out when we were dressed like that. The earliest possible would be March 2008.
