Here's me and Mom on Boston's Freedom Trail. Some of it is a red brick line like you see here (this part at the beginning had these cute ground markers) and some of it is a red paint line on the sidewalk/road. It is about 2 1/2 miles long and goes past a lot of historical sites, like Paul Revere's home built in the 1600s, the site of the Old North Church where they hung the "one if by land" lantern, and the building where the Declaration of Independence was written, etc. Very cool walk.
This one is in front of the Mayflower II, a replica of the ship the first Pilgrims came over on. My ancestor, William Bradford, rode on the original.
