There have been a few 'original' things for me this year.
1 Riviera #14 and the seasonal tees (so the par 3 doesn't play into the afternoon sun during the year).
2. Riviera #6, the donut green with the bunker in the middle.
3. Probably Rustic Canyon. Not sure which part, but #1 sets the the scene for the round, especially that little ditch that meanders wickedly on the line of play. Of course, the impact of the ditch is magnified by the ground game required at that course.
4. North Berwick West. Most of it but certainly the walls eg #3 and #13, and of course #16 green (the split green).
5. Muirfield bunkers. Tom Doak described them on his tour next door at Renaissance as half gathering, half revetted. They are unique, and effective.
6. Glenelg bunkers (Adelaide). Neil Crafter designed a half revett, half flashed sand bunker using the natural orange-tinge sands at Glenelg which mimics the playability style of the Melbourne sand-belt but without the grey sands which can compact to give the hard flashed faces.
7. Lakeside (Max Behr) #13. The short par 4 angles to the left, uphill. However, the green is perhaps 40 yards long and only 8 yards wide with some flanking hazards. Very little slope from back to front to assist the player, so the approach shot is particularly challenging, often from either too far left or too far right. The tee-shot has to hit a particular length for a particular line to be rewarded.
8. Lakeside (Max Behr) #15 and #15A. There are two holes here, perhaps at 90 degrees to each other. One is a lovely mid-length par 3 played down into a valley/swale where the green is set. The other (the A hole) is just a pitch of perhaps 100 yards, perhaps less across that valley. Played from the top of the swale to an elevated shallow green atop another swale. You don't want to be long, nor do you want to be short.
Behr created an interesting combination of wedge shots in two holes - line of play on #13 and length of play at #15A.
Thanks to my hosts on that day - Lakeside pulls a number of memorable stunts, sitting just below Universal Studios in LA.
