I'll do my show rankings of 2012 now. I've seen so many shows that it's impossible to rank them numerically but I'll group them into tiers. I didn't go to any bad shows, they were all awesome. So the highest tiers will be pretty stacked but oh well.

I'd say my least favorite show of the year was LOG because I was sick and because I'm not a huge fan, I mostly just went because it was cheap and because my friends were going and because I'm a casual fan. If I had to choose a favorite show I'd probably pick Iron Maiden / Alice Cooper in Charlotte because it was the first night of the tour and the atmosphere was electric. Not knowing the setlist was really cool and I just about lost my mind when they did stuff like Moonchild, The Prisoner, Seventh Son, ATSS, etc.
Oh, and I had tried to buy a pit ticket with no luck since February. I probably checked Live Nation at least 500 times between presale and the day before the show but no dice. Thankfully my girlfriend's brother-in-law who I was staying with has a degree in digital multimedia or something so he's a photoshop pro. The feeling of complete relief was unbeatable when I got on the rail with my lawn ticket redesigned to say pit.
