If its anything like music festivles in england there isnt much game to it....
Wear something that makes you stand out, there is no limit on what you can put on because some1 will look more stupid than you.
Have fun, its really that simple! Just have a great time there, enjoy yourself and help the people around you to have a great time.
Tbh, if it is like music festivals its more of a case of just getting a girl to see you from the crowd and then find your tent (the latter being the much harder part!!)
Seriously tho, all "normal" game still applies, just change your interactions to be more fun and exciting than expecting to have a heated debate on the state of the world economy! Short, Fun, Exciting.
