Looking at some of the comments on youtube, it appears the current 18-hole course is a replacement of an older 9-hole course. Any idea when that happened? Which course did you play?
The video said it was around 30 years ago, when land became available.
Must be 20 years since I last played it, and I remember it was noticeable at that time, the difference between the old and new parts of the course.
I seem to remember it being all uphill front 9, all downhill back 9.
Quirky, wonderful views and that tee shot on the 10th definitely make it worth a visit.
