Tom:
In my view, WS is not a great course for watching a golf tournament, particularly a major where there are tens of thousands of folks crowding views. It is something of a difficult walk; this is pretty rough terrain that Dye created, with multiple ups and downs all over the course. It's also spread out pretty far, not condensed like a lot of courses, so you have to do a lot of walking to see it entirely. A few pointers and thoughts (from '04 PGA viewing):
-- All of the tents for food, merchandise and other PGA stuff sit on a broad, flat area away from the lake; you can't see any of the course from these areas. You have to walk down a concrete path to get to the course.
-- The course layout resembles a "T," with the 1st, 9th, 10th and 18th holes the "post" of the T, and the front and back nines running out from either side of the post. Dye also routed these holes in a classic figure 8, so the holes move toward the lake, turn away from the lake, then back to the lake, before the final holes for each nine turn inland and away from the lake. Also, an enormous, densely wooded ravine separates the two nines, and there is a long, rugged concrete path that takes you through the ravine from one nine to another. Each nine essentially plays out and back, so that when you reach the green of the 4th hole, for instance, or the 13th green, you are very far away from much of anything.
-- Eight holes (3rd, 4th, 7th, 8th, 12th, 13th, 16th, and 17th) play directly on the lake, and thus are the most scenic and perhaps most fun to watch. The 1st and 10th holes take you from near the clubhouse "out to" the dunes. The 9th and 18th holes take you out of the dunes and back to the clubhouse, each one skirting the wooded ravine. All of the rest of the holes parallel the lakeside holes on each nine.
-- I actually enjoyed watching the back nine more than the front nine; it seems more conducive to spectating than the front nine, for some reason. A fun place to watch is just behind the tee of the 10th hole (Dye's favorite hole on the course), where the drive is somewhat uphill with a bite-off-as-much-as-you-choose drive, and an enormous central bunker playing a big role on how players take on this short par 4.
-- One nifty spot I found to watch some play on two holes was a small knob of a hill directly above the 13th tee (to the left of the tee, if you looking down the fairway of the 13th hole). From there, turning around, you can see shots into, and putting on, the green of the neat little par 3 12th, and then the tee shots from the 13th tee to the fairway (one of those tee shots that makes one feel small and insignificant as a golfer, compared to these guys -- they make the terrifying look routine, but that's part of the appeal of watching it, for me.
)
-- I also enjoyed watching tee shots from just right of the 17th tee -- say what you will about that hole, and it has its share of critics, it's an absolutely majestic shot from the back tees, with a volcano-like bunker staring at the golfer on the tee.
-- You can also get a good view of tee shots on 18, and shots from the fairway to the green on 18, from the walking path lining the right side of the fairway on 18.
-- I went down the #5, to see what all the fuss was about (it's the most criticized hole on the course), and regardless of its merit, it's a hard hole to watch golf, because it's nearly all surrounded by water and wetlands and is quite flat.
-- #6 might be fun to watch, if you can get close to the new green, nearly cleaved in half by an expanded bunker. I believe there is a path pretty close to the left side of the green there.
-- One word of caution -- the native grasses there can get incredibly slippery with thousands of people walking on them. I'd advise much caution in negotiating downhill walks on the grassy area; there were a ton of sprained ankles and mishaps from unwary folks at the '04 PGA.
Have fun!
