I spent this last week near Boston for some work-related training. Boston is full of Revolutionary War history, and one of the most recognized characters is Paul Revere.
Paul Revere arranged for two lanterns to be hung in the steeple of the Old North Church (seen in the picture above) to warn his fellow patriots tht the British were approaching by sea ("One if by land, two if by sea"). He then took off on his midnight ride, successfully warning those in the neighboring towns.
Today, Boston's 3-mile Freedom Trail, which several of us walked about 2 miles of, takes you by many of these historic sites, including Paul Revere's home, below. The trail itself is marked by a pattern of bricks in the sidewalks and streets, and is very easy to follow. (You can also see part of the Freedom Trail in the sidewalk in the background.) Businesses on the path such as this pub (left) can take advantage of their location, as you can see in this pub's sign.
