1. It's a nice tradition. I don't know if it is the greatest one. If it takes place after the round, that's proper. If it holds up play, it needs to be revisited.
2. The bridge should be revered for much more than its relationship to golf. It relates to the history of humanity more than it does to golf, in my estimation.
3. One never knows who does the "tweeting" for older celebrities. Jenkins has celebrity status in golf circles. He might have a staff, an intern, or he might go it alone. Tweeting drives interest and moves the needle. I've read tremendous pieces that received nary a comment, and other, more controversial (even jaded and unfounded) ones that garnered 100s of comments.
4. John, I hope that you are correct. I recall in 2007, when Colt Knost turned pro prior to the Masters. As US Amateur champion, he was eligible to receive an invitation, but he indicated that he had to get on with the business of earning money, to repay his parents all that they had given him. He has yet to earn an invitation to Augusta as a professional.
5. I prefer the less-rigid "A fine tradition in golf" to the demarcating something as the most extreme. Unless, of course, the goal is to drive interest and move the needle...
