I can see how it interests many people, but for me it is not that intriguing. At least not the first time I would go to the event... I like to walk the course and get a sense of the course, rather than spending too much time at one hole.
But if I was going twice in a week to the Waste Mgmt, perhaps the second day I would be more open to it.
My favourite thing to do when I go to a PGA event, is to walk 5-7 holes in reverse over a few hours... stop at a few holes. You see many more players like that, and seeing the balls come in rather than following them gives you a different perspective.
I have not been at that many events however. I have been to the Canadian Open, WGC - Bridgestone (great to see many shots), and Oak Hill (PGA 2014). I have been to 4 different courses for the Canadian Open however (Glen Abbey, Royal Montreal, Hamilton GCC, and Angus Glen)
