t-shirt design for Destination Unknown

[pythagoras]

help! I've been picked to design the t-shirt for our sorority's destination unknown formal and I don't know what to do. Can anyone direct me to any links or inspiration for good destination unknown/formal t-shirt designs? All I know is that it will be a formal event which we will be traveling to by bus.
