Where is everyone?

Hi all--it's getting to that time where Heather and I need to get moving on invitations for the wedding, and I want to make sure that I have a current address for some of the cousins (which I'm sure I don't) So, could I get addresses for Billy, Jason, Kristin, Steve, Karen, Mark (I know I aught to know Mark since its next to Dick and down the road from my Grandparents', but I want to make sure). I'm looking for whatever address will be current as of May 1st. Send them to my email: jmbranso@mtu.edu. Thanks!
