Bonjour Yannick,
Let me take this a step further, are we asking nominal dollars per round? Quality holes for the money? Or local (real dollars) per hole?
There are a couple of ways to look at this good question. If you are looking at good value per quality hole, WH is one of the best in the world. However, you are also looking at an area of the country where you can live on 35k USD per year and a decent muni is under $20 to play. To most people in Nebraska, 35 bucks to walk is not cheap.
Pete's example of Tallgrass on Long Island (which I have never played and is probably a good course) 40 nominal dollars for 18 holes on Long Island is a true bargain. So would Sean's Enniscrone and Carne be local bargains as well.
IMHO, most locals still see WH as a bargain when quality per hole is factored. $425 USD per year for dues, is what most of us (even in Omaha, 400 km away) pay for our locker dues at a private club.
