lots of water in a plastic bottle with squirt top, to drink and to wash off your skin or eyes, if needed
energy snacks
identification and/or emergency contact information only if you want to be cited out of jail in the event of arrest
just enough money for pay-phone, food, transportation
watch, paper, pen for accurate documentation of events, police brutality, injuries
water- or alcohol-based sunscreen
inhaler, epipen, insulin or other meds if applicable
several days of prescription medication and doctor's note in case of arrest
menstrual pads, if needed. Avoid using tampons - if you're arrested you may not have a chance to change it (tampons left in more than six hours increase your risk of developing toxic shock syndrome)
