I was out there on Monday and even with one of the smallest crowds of the week, it was clear it wasn't going to be a good spectator experience.
Following a group simply wasn't possible. The further away from the first tee you got the better things got in terms of seeing. The holes going east-west (4, 5, 13, 14, 15) were pretty easy to see. 1 and 10 were tough to see much on, 2 and 3 were OK, 8 obviously was impossible and that meant getting to 9 was hard. I didn't get to 17. 18 seemed challenging to see much unless you had a corporate ticket.
It wasn't impossible, but it wasn't easy to watch from non-grandstand spots.
