...I'm displaying my birthday golf wish for all to see --especially to those conservative officials at the USGA and Royal & Ancient who rule over how the game is played.
My desire is for the official honchos to forgo all equipment limitations. No size regulations on drivers or groove depth of irons or ball-distance confines next year. No restrictions on shoe spike patterns, rangefinder use, grip or special alignment considerations. Let the golf equipment designers go nuts and think way outside the box.
Hate to be the bearer of tedious tidings here, but the golf equipment manufacturers may do whatever they want.
Following the equipment rules of the USGA and R&A is completely, 100% optional. They are free to sell as many "non-conforming" clubs and balls as they'd like.
No one in Far Hills or St. Andrews is stopping them from doing that.
