I didn't get drunk or high last year and I had a blast! I did drink at our campsite, but I never got more than the slightest buzz. It was too damn hot to get drunk and it's so expensive for beer inside the venue. I'm planning to do a bit more drinking this year since I went to OSL and had a ton of fun drinking there, but again, I don't plan to be "wasted" bad.
Because of my career choice, getting caught with drugs would just be too big of a problem to ever do it openly at a festival like this. Don't want to get caught on a youtube video and lose my license.
