Ed, I found the following paragraph in "The Enclycopedia of Louisville," on Google Books which mentioned a few courses I did not know anything about:
"By the late 1920s the local communities provided the home for 14 courses including Crescent Hill Course, Big Spring CC, New Albany CC, Standard Oil Golf Course, Producer's Wood Pre Co Golf Course, Owl Creek CC, Jefferson CC, L&N CC, and Shawnee Golf Club. "
Earlier in the article it had mentioned Cherokee, LCC, Standard CC (the now defunct River Run site), and Audabon CC so I count 13. I was not familiar with Jeffereson CC, PWP, Standard Oil GC or that a course predates the 1952 L&N CC that is now called the Crossings. Nobody knows who did New Albany although I think it dates to 1922 and is actually in Indiana. It was a very prestigious club at one point. Probably as always creates more questions than answers.
