Quoting:
"If you have tickets for Sunday, your tickets are always good for Sunday. It has nothing to do with what round it is. If they get four hours of play in on any give day, they deem it a full day of golf as far as tickets are concerned. People with Thursday tickets should get there early if they want to see any golf because the worst of the weather is due in the afternoon and, with starting times around 7:00 AM, they should easily get four hours of play in tomorrow."
thanks for the tips; I'm going tomorrow - shaping up to be the Woodstock of golf I guess... my luck, they'll blow the horn at 1:13pm
