Courses from great golf areas if were in DC area (largely a wasteland): Knollwood (Chicago) and Century (NY Met) both would be top 5 or better in DC area.
Remote that would get more recognition if not so remote: Primland. But it would be a challenge to move the Blue Ridge Mountains.
Thought experiment that intrigues me: Bandon Resort to Eastern Long Island. I have played only Friar’s Head, but I think it is better than any of the Bandon courses, although not by much compared to BT and PD. But think about all five Bandon courses in the company of also NGLA, Shinnecock, Maidstone, and Sebonack.
Fun if purely hypothetical exercise.
