Mike, it's really going to suck losing you, but I'm happy that you will finally be able to devote more time to Amanda, finalize the plans for your wedding, and start making plans for the rest of your life. I know how much the long distance relationships suck...especially with this job. The job in Washington sounds like a great opportunity; like I told the DO, you're great management material and you'll serve them well.
I'm glad the opportunity presented itself for us to work together. You've made an impact around here for sure, and it will be impossible to replace you.
