As many hallucinogens as you can afford, is basically all you'll really need. Take as much as you can without throwing up, give it a little while for the ******** to properly kick in and then ... get funky. You'll walk around the site for a few days completely naked. Befriend all the hippies who'll use their face paint to paint your penis green and then, you'll **** up in a corn field, dehydrated, sunburnt from head to toe, with absolutely no knowledge of how you got there or any of your activities the two days prior.
You may also have a ****** of mice, nesting in your anus. But we'll wait and see on that.
