A couple things that stand out to me:
1. Almost all the courses only moved up or down no more than 5 spots.
2. There was a lot of love for Monterrey Peninsula CC. The Dunes debuted at 79, as Anthony noted, and the Shore went from 65 to 56.
3. The courses that moved down 10 or more spots:
Kinlock 52 to 66
Kittansett Club 67 to 78
Spring Hill GC 69 to 93
Laurel Valley 95 to 105
Flint Hills National 97 to 113
Sahalee 98 to 117
4. The courses that moved up 10 or more spots:
Winged Foot East 62 to 52
Shoreacres 66 to 55
Essex County Club (MA.) 91 to 73
Calusa Pines 96 to 83
Sleep Hollow 101 to 89
5. Some notable debuts are Sand Valley at 110, Stone Eagle at 111, Mamouth Dunes at 145, Streamsong Black 169
6. Bel Air dropped from 157 to170 probably because hardly any raters saw TD's renovation.
7. In the second greatest 100 there were no courses that moved up 20 or more places, but a plethora of courses that moved down 20 or more places:
Bellerive down from 118 to 144
Eugene CC down from 128 to 159
Lost Dunes down from 141 to 161
Ocean Forest down from 128 to 162
Long Cove down 148 to 168
Sanctuary down 152 to 175
Trump International (West Palm Beach) down 156 to 178
Torrey Pines down 166 to 186
Glenwild down 168 to 188
Kiawah Island Club (river) down 175 to 198
The Broadmoor (east) down 169 to 199
Whisper Rock (lower) down 172 to 200
8. Overall there were 3 new courses for the TOP 100 and 23 in the Second 100 for a total of 26 courses that are no longer ranked now from 2 years ago.
