Ran:
I'm absolutely shocked!!!! You mentioned this and Pat even read it and for some unknown reason did not pick up on its true significance!!!!
You see the USGA doesn't need to institute such a rule because they already have one. What they would need to do to institute what you're suggesting is to eliminate each and every exception to that rule which they now have in place.
But I will tell you this with certainty (and to prove that Pat was asleep at the switch!!!!), that if they did eliminate all the exceptions what they would in effect be doing is eliminating the elimination of the STYMIE!!!! You see it was the stymie itself that prevented a golfer from ever touching his ball or I guess I should more accurately say that the fact that a golfer could not touch his ball is the sole reason why the stymie was in effect in golf and likely lasted as long as it did!!!
Interesting idea on your part to keep thing firm and fast but there are probably a ton better and more effective ways of going about it than to intsitute this rule (by removing the present exceptions).
But, My God, if for some reason this were done the stymie would be back, golfers would learn how to creatively chip again, it could be the end of bluegrass rough surrounding greens, courses would be firm and fast again and in effect all would be right with the world due to the return of the stymie!!!!
Way to go Ran, and as Butch said to Sundance; "Just keep thinking--that's what you're good at!"
