This is how the U.S.S. Bowfin looks like from the bow looking towards the stern. The flag in the middle is a jack which is striped and contains a snake with the words "Don't Tread on Me" on the bottom of the flag. It is one of the first jacks used by the U.S. Navy, being flown in the American Revolution. The Secratary of Defense, Donald Rumsfeld, ordered that all U.S. Navy historical ships fly this jack until the War on Terrorism is won. That being the case, if you want to see one of these flags, there's no hurry.
