I've tried watching this Open for the last couple of days, but it's a snooze fest. The leaders don't have any personality to speak of, and after watching the beat down at Merion, the course they're playing looks like it's set up about as hard as a local muni. The greens are slow, the fairways are huge.
It will be interesting to watch the women play Pinehurst #2 next year right after the men's Open. They'll obviously be moved up quite a bit, but hopefully the USGA won't change the rough or the greens in the few days leading to the women's Open.
Back to watching the Colonial.
If the set up is easy how come so few women broke par? Wide courses don't mean easy. Just hitting a fairways doesn't mean an easy shot into the green. It's important to hit the correct side of the fairway to have the proper angle to the pin. Then although the greens are large, the landing areas to get close to the pins are small. The greens cannot be too fast because they are exposed to the wind and could get extremely fast. The modern trend in course construction is this kind of course. Look at Bandon, Streamstrong, Sand Hills, Dismal River and others as lay of the land courses not artificially confined by 1000's of trees. As Erik says, Pinehurst will have wide fairways and the original concept of Augusta Narional was wide fairways and proper approach angles.
