I live within an hour of a boarding school that several children in my town have attended. One mother of a day student that I spoke with said that if one of her other children attends, she will board. Her day student spent over 20 hours in the car a week. I have often wondered what the average commute time is for the suburban American child. I'll bet they spend a staggering amount of their childhood in a car. It is one of the reasons we have somewhat limited our children's EC committments. We always felt that "free time" to dream and pursue independent interests was as important, if not more important, than a bunch of progams that often seemed to be more for the adults than the children....but I digress.
Being a local boarder seems like the best of both worlds. For some schools, however, (Andover and Exeter), it isn't an option.
