Tom-
Good idea.....I did a very quick check (which gave me a bit of a headache). I didn't count the total courses, but I've played 24 from the first group (you've got me dominated there), 30 from the second, and 29 from the last.....grand total of 83. That's probably pretty close, but I may have brain-farted on a few.
Still.....guess it doesn't come nearly close to even the 148 listings you counted just for the first grouping. Yikes.
Maybe if I just narrow it down to public the number is more reasonable, and realistic. Though that will throw out at least a dozen of the course I've already counted above as played!
Seems a good lifetime goal at least.
I have to say to all you that would be hard put to seek out all the "undesirable" courses.....there's something to be experienced and learned from EVERY course......if not that it only makes you appreciate your home course all the better. I wish some of my regular golfers here would get out and play some obscures every once in a while, so then they'd have some perspective about the decent job we DO do here, and hopefully not complain or whine as much!
