Day’s drive or 5 hours flight - what’s the difference 
I’d look at Eckerd (FL), Agnes Scott (GA), Mt. Holyoke, Bryn Mawr, College of the Atlantic, Connecticut, Macalester (MN), Oberlin (OH). Dennison too.
A few are further away.
I do think an Occidental in CA could work or some of the schools in Portland (Willamette, William & Clark) - and throwing in a flagship - UVM.
Good luck
