Ohhh, we used the "There's No Place Like Home" last year and had these really cute red sparkly shoes on the front of lavendar shirts with the quote on the back...we also decorated our house with rainbows out front and colored the bricks with yellow chalk and a sign that said "Follow the Yellow Brick Road Home!"
We really wanted to do the "Welcome to Las Vegas" theme last year, but another chapter on our campus wanted to do it...i like the Cheers one that Sharon suggested too
