good luck with tri delta...i would suggest going to our national site and finding out about the philanthropy (St. Judes) and other things that maybe you can ask about, or say you are interested in. Maybe you already know about them, but if there is a lull in conversation, why don't you ask something like what kinds of events do yo do for St. Judes hospital or something along those lines at least to show you do know stuff about ddd.
Good luck and keep us updated on how it goes!
