The usual suspects are on the list.
Most colleges have at least one Instagram-worthy building, with or without vines or plam trees, but whether all of the colleges on the list have an entire campus that reflects the cover shot, is another story.
Sewanee (The University of the South) was just ranked #1 on another list that a friend of mine posted to her social media (her kid attends). My thought is that they just periodically shuffle these lists and repost.
