I usually play early and bring a peanut butter and jelly sandwich and a banana. Always have three or four different kinds of snack bars, Cliff Bars are good. And often also have some dried apricots in the bag as well. You never know when an extra 18 pops up, got to be prepared. And I always bring two or three bottles of Propel, plus a few powder packets if I need more water. Plain water is too boring.
