Dan Maples has three courses in the Calabash area that I like a lot; Oyster Bay, the Pearl West, and Marsh Harbour (NLE, unfortunately). He also did The Witch at Myrtle Beach, which is one of the more underrated courses among the mid-range courses there. The Pit is probably his best known course because it is controversial; I've never played it, but I understand that it currently suffers from poor playing conditions.
I've enjoyed all of the Ellis Maples courses I've played as well, but have never played Grandfather. I think he actually did more courses than Dan has, BTW.
