Wonder why it falls to you? My twentieth slipped by a few years ago. Through the efforts if one soccer mom type almost everyone was on Facebook - so it was easy. She asked me by FB of course to make the first call because I live the furthest away. I said don't make any plans around me. The thing went forward and I got the low down from a friend who still lives in the area.

If you think it's more trouble than its worth, call someone you think is at least somewhat motivated and politely tell them you don't really want to do it and if they want to see it go forward they should get a move on or maybe they can find someone else.

Just a thought.
