Olde Homestead is a lot of fun. As is Honeybrook (only time I played behind an Amish twosome!)
I love Lederach, and Morgan Hills has some really memorable holes.
Architects is a lot of fun if it's not too busy. Bad 18th hole is a bit or a downer though.
Wyncote is a great walking course that was once the #2 new course in a Golf Digest rating.
I agree with Matt on Pilgrims Oak. It's cheap, scenic, and fun.
Rees Jones "Broad Run" (Tattersall) is worth a visit if for no reason other then to study a poor course by a good architect. You can't walk this course!
-----------------------------------
Applecross is supposed to open 9 holes this summer. I drove by and it looked kinda mundane from the outside - granted this could be completely wrong (I made that mistake with my Tetherow observations last year).
================
If you're heading toward AC, do play Twisted Dune. Do play Sand Barrens. And give the fine folks at Hidden Creek a call - I don't know if you can get on, but you won't forget it if you do. Of course, Atlantic City GC is an excellent choice.
