A boarding school in Millbrook, New York where all the preppy people go, and all the people who want to be preppy go. You can sneak out into guys dorms all the time, skip classes, and guys can smoke pot in the basement and nobody will know for two weeks.
why is that girl wearing white jeans and a barbour in the spring? oh she must go to the Millbrook Boarding School.
