Revolutionary: 250 years later, the 'Liberty Tree' blooms again

Long before the first shots of the American Revolution were fired, there was -- a tree. An elm tree in a grove in Boston, where some say the Revolution truly started. It became famous across the colonies in paintings, engravings and poems as the Liberty Tree. Now, 250 years after the British unceremoniously chopped it down, Liberty Trees are springing up once again.
