The Fort, Trophy Club, French Lick Hill Course, Sultan's Run, Heartland Crossing (BEFORE the renovation), Hulman Links
Trophy Club is a BLAST to play, as is the Hill Course in French Lick. I have not played Warren (hope to soon...huge C&C fan...I live in Tampa and just joined Sugarloaf Mountain). I recently played Prairie View in Carmel...it is rated public #1 by Golfweek, but it would barely make my top ten.
Hulman Links is an interesting course...it has a wonderful layout, but it is BRUTAL from the tips...a 10 handicap would have trouble breaking 90 50% of the time IMO.
Another interesting course is Rolling Meadows just outside of Bloomington...I have not played there in 8 years, however.
Purgatory is fun, although it can be tedious.
