It's interesting looking at the state-to-state disparity in public courses vs all courses. For example, NY has 2 courses in this top 100 (Bethpage Black and Bethpage Red) and 14 courses in the Golf.com Top 100 (US), with Shinnecock and NGLA leading the way.
Compare with Florida which I think has 9 on this list and only 3 on the Golf.com Top 100 list (Seminole, TPC and Streamsong Red).
Then California has 13 on the Golf.com list and 11 on this list, so is a lot more evenly balanced.
