Ah, yes, the good old days...
We would sometimes go to MSP to play video games, just for a change of pace.
One of my best friends lived far away but occasionally transited through there, and I would go hang out with her for a few hours during her layovers.
I do remember my parents taking us kids to the airport when we were young so we could sit at the gate and watch the planes take off and land.
Any pleasure I ever derived from airports or flying is long gone now.
