I think your list is very good! You might also consider Kenyon College in Ohio. It has a classic New England LAC campus. It is best known for its writing/English programs. Famous alumni include John Green (“The Fault in Our Stars”), Laura Hillenbrand (“Seabiscuit” and “Unbroken”), Ransom Riggs (“Miss Peregrine’s Home for Peculiar Children”), Bill Watterson (“Calvin and Hobbes”), E.L. Doctorow, William Gass, Robert Lowell, and many others. Pretty darn impressive.
