I have played many of the best courses in the world that existed at the time that Cobbs was built and feel confident in saying that the original routing of Cobbs was surely one of the finest and most demanding courses to be found anywhere at that time.
It's interesting you say that, because I've also played many, if not most of the historical public courses from that time.
In fact, despite my "narrow experience", or whatever else was represented about me above, I've played all the historic public city courses of New York, Baltimore, New Orleans, Atlanta, District of Columbia, Dallas, Salt Lake City, Garden City, Sioux Falls, Minneapolis, San Antonio, San Diego, Denver, Miami, Newark, Wilmington, Elmira, Phoenix, Tucson, and others.
One of my favorite things to do in visiting any city is to find the oldest public course(s) in town and venture out to play them. Many times, no one has ever had much money to futz with them and many of the vintage architectural features and charm are intact.
I don't have to "prove" anything, and the last thing the world needs is another circuitous, long-running argument pointlessly argued without end, redundantly on GCA.
Lord help us...
Those who think my opinion (based on travels and experience) is worthwhile will perhaps find my opinion of value and those who do not (for whatever reason) will not.
