With this site and the internet, it is hard to be surprised, but here are five in no particular order.
SAND CREEK STATION, Newton, KS- I have always thought that Wild Horse was probably the best value in golf and a perfect warm-up for world-class Sand Hills. SCS is in the same mold for nearby Prairie Dunes, though the variance with is neighbor may be smaller (than WH to SH).
WILD HORSE, Gothenburg, NE- see above; loved the story and the people behind it.
AIKEN GC- Aiken, SC- value in spades, nice topography, more on the fun than challenging side, but plenty there to keep one's interest.
WEXFORD PLANATATION- Hilton Head Island, SC- no expectations- thought about skipping it- fantastic redo of the greens by the Palmer organization and a very enjoyable routing (had to be because I suffered through a historic back 9 choke job to lose my match on 18 in the DC).
DISMAL RIVER- NICKLAUS- again, partially due to low expectations mainly created by comments appearing on this site. Instead, I found a course with a lot of variety, quirk, challenge, and just plain fun. It is cart golf, but perfect for a fantastic destination club with a very complimentary sister course where most golfers will want to play at least 36 holes each day.
