... or how far would you like to drive in a car to find an open gas station at, let's say 23:42 in the evening?

Hm. The last time I tried to talk with Bob, I think I've threatened all of us with this question, on another boring lousy thursday. So. This is not an official jetphotos poll (yes in earlier days there have been official jetphotos polls, with nice colorful bars as a result), but let me give you four choices, like in Who wants to be a millionaire:
A: 5 US miles.
B: 15 US miles.
C: 20 US miles.
D: clearly more than 20 US miles.

PS: Gabriels opinion would interest me alot, because I know his home airport. Greetings, btw .
