top 3 must have camping gear at festivals

In your opinion what are the top 3 things that you must take to a festival? This excludes the obvious camping gear. I'm just trying to make this year at Bonnaroo be the best and thought this might be a good place for people who have never experienced a festival, get a good idea of what to bring and expect.

 

Festival or not, a guitar is the absolute #1 camping gear as far as I am concerned.

 

A smile, love, and understanding

 

Didjerido, Beer & good will

 

my dog ,my drum,and my kayak

 

my drum, home-made wine, and glo-paint.

 

a crunk bucket, a drum, a water jug

 

water, loo roll, wellies!

 

sleeping bag, fire, and herb.

 

i know my biggest problem at festivals is not enough money, but i have gone to a show sober as fuck, didn't even have any herb, but i still had a blast, so i think the main thing you need is a ticket.
oh yea, right before we left that show we found a bag of grass just lying on the ground. Karma
