Make that another endorsement for Palmetto. The course at Mount Vintage (also in Aiken) is interesting as well. I've also heard nice things about Aiken Golf Club.
Sean Arble--
That's great to hear about your experience with the folks at Palmetto. My dad and I played it two Junes ago, and from the moment we arrived (early; before anyone else got to the course for the day), everyone was really nice. Imagine how they treat the members, knowing how nicely they treat the guests!
