Raised in Granada Hills (Yes, I was a valley dude) -- currently in Illinois
BTW on the subject of LA traffic, my GF thought I was a crazy driver, until she spent her first week with me in the LA area on the 101, 405, 5 and 118 freeways.
She said, with knuckles and face quite white: "Why is it that you seem like the most sane driver out here, and a nut in IL?"
I said, "My driving hasn't changed, just the drivers around me. Would you like to drive?"
I hear silence for a second, and then a little whimper comes from the passenger seat, "f'ck no."
