I've been to my share of festivals, and I'm done with them. I have too big of a personal bubble. I don't like being sweated and bumped into, or being suffocated by the smell of urine, drugs, and alcohol, with the added joy of dirt in your mouth, eyes, and ears due to all the dancing kicking up the sand.
But when i do go to festivals, I'm usually in the back sitting down listening and enjoying the atmosphere from afar.
Back a while ago, i took a trip to the Netherlands and attended a weekend festival called Defqon.1 . ( hard style ) It was a blast since the location was hilly and terraced so people like me can relax on them while enjoying the large elaborate stages, fireworks and pyrotechnics.
