Download the free audio file from http://www.MP3EXP.com and bring it with you to the secret location (announced 24 hours in advance). Press play at the designated time and follow along with the others. The hilarious track will lead you on an adventure in the city where you meet new people, make new friends, and hyperventilate from laughter.
