Ok, so we just got married at the courthouse on December 23! It is pretty painless, we did it in Kansas City and you just go down and pay the $50 for the license and the $25 extra for the judge to marry you and Voila! you are legally hitched!
It is basically like a cattle call, you sit in the audience and wait your turn. I wore a red dress, he wore a black suit and tie, and it was very nonchalant.
It is funny because we were talking about it on Christmas with family and they asked how it feels to be married. We both do not feel any different, but I KNOW it will all sink in for me after March when I get to wear the white dress and have all of the pomp and circumstance of a "real" wedding :-)
Hope that helps, let me know if you have any additional questions!
