One of my closest friends has been a "rater" for years.
There are many courses, like perhaps Old Elm, who politely decline to have the "rater" trundle over to their course so that he or she may grade the facility, the course, the pace, the caddies, the conditions, etc.
These courses do not need new members, are not seeking exposure and generally do not want uninvited press. Having some golf magazine know-it-all come to their club would be considered petty and bourgeois...;-)
My input on the actual topic:
1. Chicago Golf
2. Shore Acres
3. Onwentsia
4. Exmoor
5. Knollwood
6. Beverly (but watch your wallet...;-)
7. Glen View (re-opens in May after Jim Urbina restoration)
8. Black Sheep (just plain fun)
9. Skokie
10. Flossmor
But, your friend will NOT have access to all of these courses so he will need some public access back-up:
1. Harborside
2. Cog Hill #4
3. Cantigny
4. Pine Meadow
5. Prairie Landing
These courses have already been listed and are worth playing but deliver a very different experince:
1. Medinah #3 (very curious about the RGD work on #1)
2. Butler - great greens, big course, fit for the pros, all it needs is a resort/conference center!
3. Olympia Fields - better experince than Medinah
4. Kemper Lakes - hey, if you like playing courses that hosted majors (PGA '89)
also of note:
A. North Shore - flat Colt/Allison with great greens
B. Evanston - Pritchard restored Ross
C. Park Ridge - Esler restored Ross, so much fun!
D. Ruth Lake - Art Hills did "restoration" of Langford/Moreau
E. Indian Hill
F. Westmoreland
G. Sunset Ridge
H. Chicago Highlands - new Art Hills linksy course very close to city. Best greens.
