It's a beautiful day in Lexington as the town celebrates an iconic day in Massachusetts and American history.

It all started with a reenactment of the Battle of Lexington on Saturday morning, but there are additional activities, including Lexington's Patriots' Day Parade, planned for later in the day. Neighboring Concord, which also played a pivotal role on that morning 250 years ago, is having its own celebrations, with a parade, reenactments and a block party.
