I saw them on St. Paddy's in 2005, I believe. They put on a great show, but to be honest, like many bands I feel like they were better before they got extremely popular.
Just looked at tickets for the show next week.. I totally should have bought them earlier. Only places that have them are third party brokers and they want $100/tix for what were originally $26 tickets. Obscene. I want to see dropkick again, but not that badly..
