I'm considering this. I'm already in Nashville from the 11th for Exit 111 (Def Leppard, Skynyrd, Seether, GnR, Anthrax and god knows how much else) but I would have to skip an idol of mine in Randall Munroe who is in London on the 7th. I could justify RiR if it was part of a long Americas holiday but I can't flit back for one day.... hmm we'll see.
