Do you think there is something about LA, though, which makes people there more willing to drive those extreme distances for work, instead of just moving closer? I understand LA County to be a relatively loose collection of independent communities, anchored around the city.
I hear a 120 minute commute and I'm thinking almost like a Tampa -> Orlando commute, or a West Palm Beach -> Miami commute - which I know some people do, but its not nearly as "normal" in FL to make that kind of extreme drive, and I'm certain it isn't because Tampa somehow provides more and better opportunities than, say, Burbank on its own, or Long Beach on its own, does.
