Although not technically part of the vehicle display, there just so happened to be a fuel truck out on the tarmac, so Grandma, the boys and I got a lesson in how to audit one. So they know what they're doing on take-your-kid-to-work-day, of course. (When IS that? I can't wait for that day!)
One last vehicle to see on our way out - a Blackhawk helicopter. Very impressive!
