I think that a great first hole should be a relatively easy par four. It gets play moving and if a great second shot is played a birdie can be made. Some examples: Merion East, Seminole, Pinehurst #2, Lost Dunes, Mountain Ridge, Pebble Beach, Garden City, Piping Rock, Charlotte Country Club, the Medalist, the Golf Club, Teeth of the Dog, Inverness, Cherry Hills (from the "Palmer" tee), Myopia Hunt and I hate to admit it, Congressional. I've left off National because I think the green is too severe--too many chip shots that miss the green and four putts that delay the following group(s) from teeing off. The first at Pine Valley is a very good hole, but like most of the courses the USGA plays its Open on, they're just too tough a start for my liking. Baltusrol, Oakmont, Southern Hills, Oak Hill, etc.
