Jeff can tell you what he has planned. People start showing up Thurs night - Friday. Friday is whatever falls into place for those present (maybe just cooking burgers on the patio), Sat. is the "official" functions. Sunday people start filtering out. Last year some added a New Orleans stay on the end.
Friday and Sunday, if you are around, there will be a bunch of folks who won't tell you you got "the good cancer", and will understand when you need a pad break. There isn't much like being able to have a real conversation with guys who understand the basic premise.
