Hey! We have Up 'Til Dawn at Christian Brothers University (of course! It is in Memphis along with Saint Jude
). Actually I think the old Greek Advisor at CBU was one of the founders of the whole program (at University of Memphis).
We had teams of 5-6 for letter-writing parties, and we had a 5K. Teams were also encouraged to do individual fundraising, ie canning or a date auction.
Good luck! As Morale Chair, maybe you could paint banners and put em up on campus, or put a nice note (mini-flyer) of thanks in the mailboxes of all who register.
