Crane, OR is I think the only public high school that boards its students in dorms during the week. Its geographic area is 7700sq miles. (The size of Massachusetts) It has 50-60 students.
If I remember correctly my students in Glenallen AK used to be bussed from up to 2.5 hours each way! I always have thought that was so silly to still have daily classes. Why not just once a week and the whole day is filled with socializing. Humans get an idea in their heads like "how school should be" and just can't let it go...
