KC is four hours from me and where I constantly go for concerts. I had two tickets, but I sold them on ebay. I can't get off work, so I'm not going anymore. I would skip work, but we have a points system where after a certain amount of points, you get fired. Calling in would put me right at the limit.
You'll like the Uptown. It's a nice venue and where AFI played that last time around. It's just big enough where you can fit a bunch of people in there but it's still really intimate. It's pretty easy to get there from the airport, also. Have fun! Know that I'm very jealous of you!
