As much as I hate what Green Day has become, I definitely wouldn't be opposed to seeing them again. They were great when I saw them in 2005 on the American Idiot tour. When it comes to their tour routing, They tend to do weird routing when kicking off a touring cycle. I saw them in Manchester and the other two New England shows they played were in Portland and Amherst, Mass (which is where UMass and pretty much nothing else is).
