I used to work at Ames in a facility a stone's throw from McMoon's (not singularity University hah).

Heard that the guys who worked on this stuff in there were super crochety. I went over there once to check out some old aerospace equipment they had hanging out in the back (I think it was some decrepit rocket engine), and they gave me a classic 'you kids get off my lawn speech' - until they found out that the friend I went with had a PhD in aeronotical engineering. They lightened up after that and we had a great conversation after that. What a wacky group.
