Brian says semi-private and John K says very private.....my experience there (about 5 rounds played, and the course itself, architect and owner all featured in separate chapters in my book "Golf Charms of Charleston") would vote for private, though perhaps things have changed in the 3--odd years since I last played there?
It's a fun round, very wide-open and windswept, with HUGE (for Charleston, anyway) elevation changes--downhill off the first and 10th tee, way up to 9, I think 15, and 18 green. My problem is that BB is the only Strantz Course I've seen in person--never been to Tobacco Rd, or Monterey. But I know it has a good reputation in Charleston as one of the nouveau courses in the region worth playing.
