I wear cargo shorts. I refuse to carry anything that doesn't fit in the pockets. I have a very small cellphone, a very small camera, and a small vinyl envelope to carry tickets and money. On days it may rain, I carry a tiny disposable poncho. On chilly mornings, I may wear a light sweater, and tie it around my waist when I don't need it anymore. I buy water when I need it (not worth the small savings to carry it around with me, IMO). I put my sunglasses on a strap thingy. I move very quickly through the park, and avoid security checks. It is SO liberating to not have anything in my hands or hanging from my shoulders!
