Whats the difference between U.S.open courses and the PGA championship courses.....?

USGA picks the hardest courses and makes them even harder. PGA is easier where as the USGA likes to see clubs break it seems.

The courses for the PGA are usually pretty fair... US Open courses are seemingly designed to be as difficult and frustrating as possible... which isn't very fun to watch and probably even less fun to play.

Actually, there have been golf courses, like Oakmont and Baltusrol, that have been used for both the PGA championship and the US OPEN. The course setup is different in each event. the USGA, who administers the US Open, believes par is a good score, and par should be defended. Therefore, they make rough very high, or stop watering greens, etc, etc, to make players struggle to break par. The last two US Opens, 5 over par won the tournament. The PGA sets their courses up in a way that seems to ecnourage a winning score of 2-7 under. Its just a different philosophy of course set up. I used to be critical of the way the US Open sets up their golf courses. However, now that the ball goes so far, and the drivers are taxing the limits of USGA conformity, most guys on tour are hitting the ball 300 yards= off the tee. You only have so much land, so the golf course cannot be made infinitely longer. So, high rough, and very fast greens are the USGA's main defense. The PGA has been very creative in choosing their sites. For example, Whistling Straits was the site a few years ago. Soon, the Ocean Course at Kiawah, a golf course I have played and absolutely love, will hold the PGA. The USGA seems to have a rotation, like the British Open. They seem to use Pebble Beach, Pinehurst, Oakmont, Bethpage Black, Winged Foot, Oakland Hills, Shinnecock Hills, The Olympic Club, etc at most of their opens

Don't really know.
