I play a course fairly regularly that has only two bunkers. One back right on a downhill par 3 which is pretty much out of play, the other in the corner of the dogleg of the short par 5 that follows it. It doesn't suffer at all. It is interesting that there are some deep grassy hollows in a few places that may have been intended for bunkers at one point, but were left as grass. Honestly, I think they ought to just fill in the remaining two, the one on the par 3 wouldn't be noticed, and the one on the par 5 is a bit over 200 to the flag so a deep hollow filled with thick rough would be just as unlikely to be a "go" for anyone but Tiger anyway.
Until this course opened and I starting playing it, I would have never thought a course without bunkers could work so well. While I'm quick to agree that bunkers are a haven from the surrounding features on many courses (I aim for the damn things on tee shots on par 4s or second shots on par 5s when I figure I can't actually get on/hold the green since I figure it is an easier play for me) I figured they were necessary to create strategy for the average player.
What it really does is open up the true strategy for these golfers. Without the artificial constraint of being told where they should and shouldn't play due to their fear of bunkers, they have to really consider the strategy inherent in the terrain and the green. I've played with some people out there before who never mention anything strategic and they'll tell me stuff like "I always try to drive to the right side of the fairway on #6, the green runs away from me if I'm hitting from the left". Really amazing how avoiding bunkers, having little water in play and little OB in play opens people's eyes. This isn't a really tough course (70.7/127 from the tips, but it has 6 par 3s and 6 par 5s so it stands to reason the course rating runs lower than usual) and the lack of obvious trouble gets people wondering why they aren't killing it and after playing it a few times even architecturally clueless people you thought were lost causes appear to begin to notice the cause and effect of where they should and should not play. They actually see the strategy!
I think bunkers that exist without any particular reason (which is 99% of them in the US, IMHO) may serve to cover up any underlying architecture. It is the golf architecture equivalent of posting something on GCA in BOLD RED CAPS [/RED]. The eyes of most players are immediately drawn to them, and everything else is drowned out. How many times do you have someone pointing out or mentioning a useless and easy to escape bunker, and missing the true strategic features of a hole? Of course, such bunkers do serve a purpose, a course without any decent architecture can use lots of useless bunkers to hide the fact that beyond them, there is no other strategy, so I guess they have their purpose for poor designs.
I played there last week (and hope to get in one more time tomorrow if the rain looks to hold off) and took some pictures, because I think it is a pretty interesting course and probably not what someone might expect would be done with Iowa farmland. Plays more like a links than anything else in Iowa or the surrounding area at least until somewhere in Nebraska. So hopefully sometime soon I'll get them out of my camera, see if they turned out halfway decent, and post them here for all to see and critique. If I play tomorrow I might bring the camera again to add a few more and increase the chances I have a few pictures they don't suck and serve the capture the wacky elevation changes going on.
