What's open and closed on Martin Luther King Jr. Day in Mass.

Martin Luther King Jr. has a deep history in Boston. King earned his doctorate in theology at Boston University. He met his future wife, Coretta Scott, here. He was a youth minister at the Twelfth Baptist Church in Roxbury. He lead the first civil rights march in the Northeast from Roxbury to Boston Common in 1965 and addressed the Massachusetts Legislature.

There are many opportunities to honor him on Jan. 15, Martin Luther King Jr. Day in the Boston area. (Check out some suggestions here.)

One small way to honor the civil rights giant is to begin your day, as my elementary school did each year, by listening to his famous "I Have a Dream" speech. A recording of the address, delivered on the steps the Lincoln Memorial in Washington D.C., along with the full text is available here.
