Perhaps your history teachers failed to alert you to these Civil War facts: Jefferson Davis nearly got mugged by an angry female mob; Abraham Lincoln loved the Confederate anthem "Dixie," and Paul Revere was a Civil War casualty.
Heading for the Massachusetts Turnpike, a Mercedes sedan closes in on the back tire of my bicycle with an aggressive honk. Less than a mile of Boston's streets have designated bike lanes, and Commonwealth Avenue - where I'm trying to avoid construction sites and deep trolley tracks - is not one of them. "Stay close to me - this traffic circle might get hairy!" shouts Andrew Prescott, one of my guides. Dodging rush-hour traffic isn't easy, and with a few hours still to go on his Paul Revere Ride to Freedom tour, I'm wondering if I'd be happier straddling a horse.
