Gate numbers! A nice ordinal number that helps air travelers know where to go to catch their plane. Denver International Airport (DIA), where this picture was taken, has 95 gates.
DIA’s motto: Together We Soar!
Pierre Regional Airport (PRA), as in Pierre South Dakota, has one gate. At least it did three years ago when I last flew there. I see they have a new-and-improved airport. Maybe they have two gates now. Gate numbers are less important at PRA than at DIA (PRA agent: “See your plane out the window? Walk over there!”), but for consistency sake and in case you get a non-talkative agent, gate numbers are needed at all airports.
PRA’s motto: Doorway to the World!
Motto’s are almost, but not quite, as important as gate numbers.
