Got my tickets for this too, although why they have to drag it out over three days is beyond me.
Looking forward to seeing Dragonforce, Avenged Sevenfold and Alter Bridge there, should be a good one.
Also going to Monsters of Rock on June 3rd - finally get to see the great Ted Nugent! Along with Queensryche, Journey, Thunder, Alice Cooper and Deep Purple.
Off to see Whitesnake again this year, they were fantastic last year, and hopefully seeing Maiden in December with any luck. That's the few that come to mind at the moment.
