Tony,
I think many of your guesses were pretty good. I agree #22 looks awesome, I'm not surprised its Greywalls.
1. #10/11 at Arcadia
4. Looks like it could be #6 at Angels Crossing, but its an odd angle that doesn't show the green so hard to be sure.
6. #1 at the Dunes Club
8. #7 (?) at Kingsley
9. Wuskowhan Players Club #4
11. Lost Dunes #2
17. Well...it sure looks like a Jim Engh bunker and its not Tullymore so must be True North.
Sean,
Its interesting how folks have different tastes. I'd have chosen #22 as most interesting and the one you picked I barely looked at until you re-posted
No idea where it is though...
