So I got a handful of beers (naturally), and was hurrying back to the gate when I heard that "beep beep beep" of one of those airport carts. I look back and it's a redcap with an elderly passenger. So I hitched a ride (the terminal was deserted--it was maybe 10:30pm).
The look on the faces of a whole 757-load of passengers when we drove up to the gate was priceless. (I did get multiple evil-eyes from the SAS stews). I had to note where they kept the booze and helped myself on the flight to Copenhagen, so I never officially was cut-off.
Spent a memorable couple of hours at O'Hare, if I could just remember them... ;^)
Worst experience was trying to race across Wayne County Airport in 5 minutes for a connection to O'Hare. NOT FUN! As wild as some of my sprints in DFW have been, nothing was ever that bad.
