How 'bout: Forget Tibet. Free Ithaca.
Not bad. Very good actually.
I only see one problem: the slogan will be misunderstood by the dominant lefties of Ithaca who will think it's a call to make Ithaca even MORE socialist.
I think I prefer the "city of evil" sticker if for no other reason than the fact it bug people so arrogant as to brag how "enlightened" their city is nuts.
