I love the course, but I will admit that I am not a fan of the 2nd. If that hole didn't have Donald Ross's name attached to it, I think it would be reviled.
The 4th, on the other hand, is one of my favorite par 4s anywhere. I remember the first time I played the course, I wen't over the green on 1 and 3, and the guy I was playing with reminded me that on a Ross course, short is always better than long. So on the 4th hole, I hit a good drive that went to the bottom of that fairway depression, so I couldn't really see the green. I goy my yardage and played one less club. Hit it perfectly, only to hear the guy say, "oh, you don't want to be short on this one." Little did I know that the grand canyon fronted that green.
The tree clearing on the 5th has turned one of the weaker holes on the front 9 into one of the best. And the green on the 7th when they have the speed up is virtually impossible if you are above the hole.
