As PngnTrax suggested The Wizard of Oz is a good idea. If you wanted continuity with that on bid day you could use the slogan "There's no place like home" That was on the bid day shirts for my chapter a couple of years ago. We had our letters and Bid Day 2000(obviously would be 2002 now) on the front corner and on the back we had a black and white pic of a little girl sleeping with a stuffed lion (our mascot) with the slogan I gave above. They turned out really cute. Good luck with everything
