This page from an old book on U.F.Os was scanned and uploaded by wackystuff on Flickr. I am not sure what purpose it served in the book it appeared, but I suggest you print it out and keep it in your wallet. That way when you do encounter a U.F.O (and you will this week), you can pull this out and circle the one that it most closely resembles. I suggest you also carry a pen or pencil for doing the circling.
