Step 2: Tell your posse you’re dipping. When it comes to tracking location, festival-goers are not unlike park rangers. They travel in packs, maintain a well-marked HQ (read: balloon), and when one of their own goes missing, a manhunt will almost always ensue -- especially should certain festival antics come into play (we mean hula hooping, of course).
Step 3 (if there’s a camping area): Go there. If you can’t find your tent (because of all the hula hooping), or don’t have one, hide between the sea of others and pitch your own.
Step 3 (if there’s not a camping area): At OSL (Outside Lands), there’s no camping allowed, but what it lacks in tents, it makes up for in woodsy paths that lead to smaller, secluded stages. Go to one of said empty stages armed with a giant sheet or blanket.
