Bringing my digi cam. It should't be too much trouble as it's small and I'll only be taking a few shots/vids of each band so as to maximize memory space. Plus my little cam has made it through many a squished pit, it's tough like me.
How many concerts of this caliber let you bring in cameras? Most of the bigger shows I've been to will confiscate your camera just for trying to bring it in. Bringing a camera is a must. I took almost 300 pictures last year and plan on taking around that many this year.
My solution for that is I purchased a portable hard drive that uploads memory cards in a couple minutes and seperates them into folders. It holds 40GB and only cost me $120. Another year I escape and I dont need a laptop.
