U.S. Route 60 Virginia Beach
Virginia Beach, Virginia's largest city, famously posts these unique anti-profanity/noise signs around the beach front. Apparently, according to VA law, "If any person profanely curses or swears or is intoxicated in public, whether such intoxication results from alcohol, narcotic drug or other intoxicant or drug of whatever nature, he shall be deemed guilty of a Class 4 misdemeanor." Although one would think that cursing sober (!) would be protected by the Constitution.
