Cool!
I used to work in Albuquerque, and had security clearance to enter Sandia National Labs (it is on an air force base that also doubles as a nuclear missile base) as part of a research collaboration I had going there. Crazy shit they had going on (much of it around energy research actually), include sometimes where they would make these cryptic announcements like "You will hear a very loud explosion in the desert south of the base at 1:15pm today. Please ignore."! Everything from fusion reactors to all kinds of crazy stuff going on there!
