Played there as well on Sunday. Course was really backed up for us, took 5 hours; my group normally plays in 3.5. Had 5 groups on number 9.
I know what you mean about fixing ball marks, we were talking about that as well on Sunday. Seemed to be worse than normal.
When did you go out? We teed off around 1:30 and it was dead. Probably because all of the sane people played early to stay out of the heat
