Gamble Sands is excellent. The setting is beautiful, and the course is enjoyable for a wide range of skill levels.
Instead of traditional tee boxes, the markers are set on broad expanses of fairway-like turf. The length of the course and playing angles can change significantly based on markers selected, and the course can be set up to play differently from day-to-day. On tee shots, for example, bunkers that can be readily carried one day may be out of reach the next because the tee markers have been shifted dramatically. In a 15mph breeze, which must be common given the course's setting on a high plateau above the river, GS could be set up to be challenging for even very skilled players.
The weakest element is the green complexes, only a few of which contain significantly undulation. GS does not present that many interesting short game challenges.
