We hope, of course, you won't get sick or hurt ... but being radically self-reliant also means remembering to bring a first aid kit for treating yourself or your campmates for minor injuries. Be sure to bring one! If you run out of bandaids, vinegar, tampons, etc. your neighbors can help, and our emergency services people can help, but you should have a meaty stash of first aid supplies on hand when you arrive on playa.
Sorry — did you say vinegar? Yes!! One of the top complaints is playa foot. This is your skin's response to the alkali conditions, and it's not fun. A soak in a 4:1 water to vinegar mix for 20 minutes each day will help this.
