I used to think Mike Cirba was one of golf's most prolific travelers. Then earlier this year I played with a Golf Digest rater who has played either 2,200 or 2,500 courses. I misplaced his business card, but his first name is Terry.
Last year I played some 90 courses, with around 80 of them for the first time. Terry played something like 150 new ones, a lighter than normal year for him, and he probably has at least a decade more ahead of him. I wonder what the record for most courses played is.
Regarding Augusta National, my favorite GCAer has played it. I don't know if 100 of our compatriots have played it, but the number is probably pretty high.
I don't know if Ran has the interest or the site has the bandwidth, but I would be willing to cut and paste my list of courses played from a spreadsheet. I wouldn't be surprised to see a substantial majority in the collective list.
