I realize this is a rookie question, but I'm a Coachella rookie. This is blunt: how do I prevent all my stuff from getting stolen on the camping grounds while I'm at the festival all day? I know they say to not "leave anything valuable," but does that include EVERYTHING? I mean yeah I could always have my wallet and phone, but what about clothes, medicine, etc?

Sorry for this question, but feel free to make fun of me.
