Mr. Morrow, I think I enjoy your posts as much as anyone's on this site.
And on this issue I agree with you.
Of course, it's easy for me to agree with you, as I'm not very good. Knowing precise distances doesn't tend to help me much, and I find that I enjoy the game much more having to try and figure it out for myself. Also, when I'm playing a "competitive" round with my friends, the stakes are low. A few bucks, or lunch, or beers. With so little on the line, I'm willing more often than not to let my own ability to judge distance be part of whether or not I come out on top. I might look at the 150 marker over there somewhere, and take that into consideration, but it's still a best-guess-timate.
But that ship has sailed, at least over here, and you're not going to ever talk folks out of walking off sprinklerhead distances, or using yardage books, or gps-distance figuring machines. For a lot of folks these tools ADD to the fun, instead of lessening it.
