I wasn't able to make it out this year. But I agree the level of flipping is pretty disgusting.
Not that I'm interested, but I'm pretty sure the *only* people who bought the Dave Matthews Band box set were flippers. Ebay is chock full of them. My only consolation is that some of these tank pretty hard. No ones interested in them, and you can end up getting them a little cheaper than their MSRP after a month or two. At least that's what happened with the Flaming Lips box set a few years back.
