I think each area has its own type of transport for the kids? It all has to do with their "nearest appropriate school" or some such verbiage. I'm trying to sort it all out myself, seeing as I'm bringing two school-age monsters over with me.
Public transport doesn't really bother me, though. When I was in 1st grade in Coral Gables (Miami) I rode a city bus to school. Then again, that was the only time I ever rode a bus to school. Lived within walking distance of every school I've attended since. Hoping for the same with my boys, but I doubt it.
