It's time for the thread author to put up. These are the most forgettable PGA sites of my 47-year era:
Sahalee, Kemper Lakes, Columbine, Tanglewood, NCR...nice course, I'm sure, even some terrific champions, but not where the PGA needs to be.
The primary question I would have is, can you drop your PGA in a large metropolitan center that is not yet exploited by major championship golf and represents ? These would be areas like Indianapolis, Dallas/Fort Worth, Cleveland, Denver, Minneapolis-St. Paul, Tampa-St. Pete, Memphis and yes, even Buffalo-Niagara Falls (more on this later.)
Rochester is #60 on the wikipedia list, but is golf-mad and hosts a great tournament. San Juan, PR, is #21 but I wonder if it would draw galleries to the event. I know that Buffalo-Niagara could not sustain a second-tour event (Nike Tour) back in the 1990s, so it's doubtful that it could muster the troops to host a PGA. Therefore, I cannot base any proposal completely on population density. If the intent of the PGA (assuming that funding is in place) is a grow-the-game initiative, then cities like Albuquerque, Little Rock, Des Moines, Winston-Salem, Boise and Spokane come into contention.
To avoid turning this into a wistful daydream of an exercise, I need to combine my critical factors and come up with sites that:
A) have the on-site infrastructure (potential or realized) to hold this event;
B) possess enough of a local or regional enthusiasm for golf/sport to draw paying fans;
C) claim corporate presence to support the tournament in that manner;
D) have the off-site infrastructure (roads, lodging, parking) to prop up the event.
Here is my list of courses:
Shadow Creek -- Las Vegas, Nevada
Canterbury -- Cleveland, Ohio
Minimichi -- Memphis, Tennessee
Brickyard Crossing -- Indianapolis, Indiana
Dallas National -- Dallas, Texas
Chambers Bay -- Tacoma, Washington
Oak Hill -- Rochester, New York
Whistling Straits -- Sheboygan, Wisconsin
Riviera -- Los Angeles, California
Shoal Creek -- Birmingham, Alabama
The list is a blend of six new and four traditional sights. It's a list that will not please many, but does address my principal concern of metropolitan/regional potential or proven fan and infrastructure/extrastructure support. It also makes an effort to introduce as many unique regions as possible to the mix.
