Not OP, but as someone who also moves around a lot, I'd say a few. Mainly, you don't get too entrenched in the local culture. You learn to kind of just be able to blend in with anyone. I could talk to some blue hair about radical ideas today, talk TCP pros and cons with some reserved networking guru tomorrow, and talk pro wrestling with a 50 year old redneck trucker the next day. Not that I'm super knowledgeable in all of those subjects, but would be just as comfortable doing all three. It's not as simple as having some extroverted ability or anything - anyone could do that, you just learn enough about people of different backgrounds and regions to understand how to interact that you really only get through exposure.

You also don't hold awful stereotypes that most people have - even most of those in a place like here. The south isn't all racist, the coast isn't all snobby, the southwest isn't full of dangerous cartels murdering everyone, middle America isn't a bunch of uneducated hicks, etc.
