Okay, for all those last minute packers, I need to add one more item to your list of things to pack. I'm sure you've seen a dozen different sites of what to bring to Blizzcon. But I'm not sure I've seen the most important thing on any of those lists.
Seriously, folks... do yourself a favor. Stop by any local drug store or whatever and pick up a set of earplugs. Last year Lvl 80 Elite Tauren Cheiftan was loud. I'm sure Ozzy Osborne will be even louder. You only get one set of ear drums. Please attend Blizzcon responsibly and protect those ears.
(I realize I'm getting older, but if you get good seats for the closing show, you'll thank me if you picked up earplugs.) You'll be able to feel Ozzy's sweat (or whatever) and still be able to hear your friends afterwards as well.
