The "Crown Jewel" was a combo of all the courses I believe, where you play around the rim of the whole hill. John wanted me to make extra signage for just that.
Ohhh....That sounds super awesome actually - I'm so doing that next time I am there. Was it still supposed to be 18?
There's a few combos written on the wall in the clubhouse as well. I remember a BB/Gold combo that's on the left wall after you walk in. Sounded fun.
Guesses at Crown Jewel:
19 holes
BB 11-12
Granite 13-14, 9-10
Bear 12-15, 18
Gold 8-18
28 holes
Gold 6-13
BB 4-12
Granite 13-14, 9-10
Bear 12-18
Here's the map - tough to find a loop through all of them that doesn't involve going way out of your way...
