How about if everyone that attends wears a t-shirt (Ford - of course) that has their FTE Username on the back?! You could have it done at a t-shirt shop or use permanent marker.
It might be kind of fun to put a face with a screen name
BTW, I don't know if hubby and I will be able to go or not. ALL of our family is in KC and we usually drive back there every year, but funds are tight so it is still up in the air.
