I was on a tour of a museum at Flying Cloud MN (Ain't there any more) -
there was a bunch of people following the guide, so at one point they turned
right, I nudged my brother and we (and the kids) turned left...

They had a B-17 with a bunch of guys in it that had flown during WW-II and
since we had disconnected from the group we had time to sit and chat with
them while they waited for the next tour group to march through.

I did my primary training next to that museum. It was intimidating to be
a student pilot doing touch and gos in front of their grandstand on show
weekends with all the old-timers hanging out watching. But we got to see
all kinds of interesting old aircraft flying. Taxiing behind a PBY, for
instance. Or being cleared into position and hold with a caution for
wake turbulence from a P-51 making a very low pass right over your head.
