Nearly every person that moves to my area (plus any local teens who haven't come across this info before) eventually has the same brain-hurty conversation.
BG: About an hour from MyTown, out in the middle of a desert, is a nuclear research facility, which is commonly referred to as The Site. Among the many people who work there are those who are training to serve on Navy nuclear-powered submarines. So we get some version of the following:
Local: blah, blah, blah Navy guys.
Local: Yeah, *short explanation*
Newcomer: Oh, ok. Wait-- sailors. Stationed in the middle of a desert. *sproiinnng*
In San Angelo you had a version of this
Civilian: Why did you move here?
Military/Military Spouse We are stationed at Goodfellow AFB
Civilian: Cool what branch are you/spouse
Sounds brain hurty if you don't know that Goodfellow AFB has Language training for all branches of the military and a few other agencies.
Some other things that hurt our brains until explained by a local
We had NEVER seen so many Hawaii and Alaskan plates on cars - apparently those are considered overseas postings and the military will ship the car as part of moving. (Not Military just what I was told)
Seeing children riding in the back of patrol cars every single day. I'm not talking kids old enough to be arrested (10 and up) but itty bitty things in car seats and boosters. The San Angelo Police Department has at least some of the patrol officers take their cars home*.. They didn't use them for personal business, but were allowed to drop off and pick up their kids on the way to and from work. There was a 24 hour child care center down the street from the police station. If you were in the area just before or after evening shift changes you would see kids in the PJ's getting out of or into police cars.
*The idea was having visible cop cars out and about especially in certain neighborhood would cut down on crime - also in the case of a citywide emergency the cops could Dress at home and go directly to were they were needed with all their equipment instead of going to the station and then going to the emergency.
