I just had to mention that I am getting married (and live) in Colorado too and am so glad that we have this rule in place. We have decided to solemnize our own marriage, also. I've always hated that someone ELSE has to declare you married, and even worse that there are minimums to what MUST be included in a wedding ceremony in many states. If two people are making this committment to eachother, it should be us who make it legally binding, not a judge, priest, or anyone else. Not to mention, as you said, it makes the process so simple. Hooray for Colorado (as I believe its one of very few states that allow this).
What part of Colorado are you in?
