Lots of places. My mom was in the Air Force, so we moved whenever the Air Force stationed her somewhere else. The simplest answer I could say is "the Midwest", because that's the only region I've lived in the US. I lived in a few foreign countries, but we didn't get out much, so it didn't really shape me.
If someone asked me where I'm from, I'd likely tell them the city I live now out of simplicity. I lived here a year and a half or whatever during my teenage years, and then moved back here 5 years ago. At this point it wins by default, haha.
