To gdel, since you mentioned Tigers group, you might want to look into following him during the practice rounds. From what I hear, he likes to get out there when the course pretty much opens. That would probably be the best way to follow Tiger since you won't have to deal with as many people as during the tournament.

I like to follow players for several holes, sometimes even a whole nine during the practice rounds. Then, when it comes tournament time, I like to stake out a spot and stay there for an extended period.
