The PGA of America, which, like the PGA Tour, operates under U.S. Golf Association rules, now attaches its commercial name to golf courses, most of them fabulous, most of them new and most of them expensive as hell, all around the country. The curmudgeonly will note that they set up for the pro shop, meaning the distance between greens and the next tee are often so great that one's virtually forced to rent a cart, creating additional revenue for the PGA establishment. The caretakers of the bottom line at PGA courses don't want you to walk, they want you to rent a cart.

But Casey Martin and seven of nine Supreme Court Justices represent a threat to the rules of PGA Tour golf, rules that must be respected and protected. Odd, the PGA Tour, which claims that the sustained integrity of the game as its goal, has become practiced at looking the other way as its members break the pre-existing laws of the land. PGA Tourists have stuffed their pockets through commercial endorsements of golf products that they don't use and wouldn't use outside of an infomercial. This is in violation of Federal Trade Commission statutes on celebrity endorsements. We return to baseball and running to first base.
