That's amazing news! Congratulations! Really happy for you and Kathryn.
Funnily enough, we might be embarking upon the same process in the not-too-distant future, but in reverse: my US-ian soon-to-be-wife (we just got engaged and plan to get married next summer) and I are thinking of moving (back, for me) to the UK...
Anyway, I hope you'll continue chronicaling your adventures either here on an another accessible space. Seems like the most exciting stuff is yet to come!
