I'm going to Bonnaroo for the first time this year, and does anyone know what the security is like? The website says they search all the cars, but is it really that extensive? I plan on bringing some "supplies" to use, and trade, so I wouldn't want to get caught. I have heard once you get inside it doesn't really matter what you do. Can anyone shed some light on this for me? The line up is awesome I can't wait.
