World's Largest Human Peace Sign? At the end of our peace march here in Ann Arbor, we're going to funnel people into a giant peace sign on the diag at the University of Michigan. Searches through the Guinness Book of World Records site, google, and a call to the Ann Arbor Library reference desk turned up no sign bigger than "a few hundred" next to the Washington Monument last October. Since we'll have a banner-towing, picture-taking airplane flying overhead, we should have some great pictures!
