To weigh in on some of the comments above:
Longaberger is a bit out of the way, but it is worth seeing. While you are out there, stop by and hit Granville - the Ross holes are wonderful, but, as Dan mentions, the other holes stink, but it is like a living museum of Ross.
I haven't heard much about the CC of Dublin here or elsewhere. I stopped by and played it just after it was opened, and, in general, was pretty impressed with the holes. I didn't care for all the man-made water hazards, as they detracted from some pretty good golf holes, and, in general, was pretty impressed and thought it might show up on someone's "best-new" list.
Cook's Creek is certainly a fine course as well.
