I figured out what they did by going to their site (although the site was no help other than to pimp the "two new courses", WTF that's a stretch considering they were only re-routed). Had to stare at the scorecard for a bit but it makes sense.
The original #10 for the Monument is now #1. The original #10 for Pinnacle is now #2. The yellow line I drew was the original way to get to #10 of the Pinnacle, it was goofy and you literally had to drive through a neighborhood for a couple hundred yards. The original #18 of the Pinnacle is now #10, and then it swings around to the original #11 and the rest of the holes follow their original numbering. It makes sense, the neighbors are probably happy, but there is no longer a return to the clubhouse at the turn.
