I grew up in the 214 and it's still the 214. I went to school in the 512... left... went home. Community college in the 972... Took a year to work in the 303 (now 970) in what used to be Texas, but is now called "Colorado". Returned and did the 972 before finishing my degree at THE 512.
Then I moved out to the 310 (and later the 323) in the City of Angels. I would drive back and forth, so I would take the 30 to the 20 to the 10. (It's very 310/323/213/818 to say "The ##" instead of "I-##" like in Texas.) I drove through the 817 and then the 432 (where they were missing their Village Idiot) before hitting the 915 on my way out of the state.
I've driven over most of the state. Obviously not all the little towns, but I've left the state taking every major highway possible, so I know the big & medium-sized cities. And then it's impossible not to meet people from everywhere when you go to college.
If you have any questions, feel free to ask.
