If you don't want to carry a bag, cargo shorts with lots of big pockets... Bought them at the gap 2 days before leaving last year... they were $16.00 marked down from $39.00 since the gap had moved on to winter gear already. (It was the second week of June, so of course that makes sense.)
Well, obviously! ;D
Everyone's pretty on-point with their lists. I'd add a fleece, especially if you are not planning a trip back to camp in the evening. It can get pretty cool in the evenings after spending all day in blistering sun. Also, it makes for a nice pillow for any down-time napping.
I also bring something to read in case I'm left standing around between sets.
*i like coconuts, you can break them open they smell like ladies lyin in the sun** *Hell I don't even know where I am** *for now I must sit here and ponder the yonder: The herbivores did well cause their food didn't never run** *We listen, if it feels good We shake** *You made a big impression for a girl of your size, Now I can't get by without you and your big brown eyes.**
Cash, schedule, phone, digital camera, lighter, party supplies, sunglasses(day time). I put most of the items in a ziplock bag so they do not get wet. I also carry a cheap rain poncho. I usually wear cargo shorts to make it easier. I do not think this is that much.
