It's Saturday, Dec. 15, Bill of Rights Day. Happy birthday to comedy genius Tim Conway (1933), whose real name is Tom, but he had to change it to work in Hollywood because there already was an actor named Tom Conway. Today in 1791, the first 10 amendments to the U.S. Constitution, known as the Bill of Rights, was ratified. Expect some rain in the morning, with a light east wind and a high in the upper 40s. Here are a few things to do after you've exercised your right to free speech today:
