Looking at the trail going through the area near the Old State House, it flows in a fairly linear fashion. It comes up along the side, cuts in front of the entrance to the State subway stop on the Orange Line. then cuts through the main intersection via crosswalks and onward to Fanueil Hall. One observation I had seen when looking at the surrounding area. a lot of vendors have set themselves up either right on top of, or right on the freedom trail line. I unfortunately do not have a picture of this at the moment. But this was happening not just near the Old State House, but down near Faneuil Hall and the markets, even more vendors were set up right on the Freedom Trail. This can attest to a sort of blending of the modern and the historical of the Freedom Trail by allowing the walkers along the trail to see the historical sites and experience more modern foods along the way.
Another thing that I had noticed about the Old State House area was that a lot of the walkers on the freedom trail really only went into the middle of the intersections and took a picture of the front of the state house instead of actually going inside of the state house. This could be because when people are walking along the freedom trail the entrance to the Old State House isnt terribly obvious. If anything the entrance to the subway station is more obvious than the entrance to the historical part of the area. A use of the tags could be to point the walkers in the right direction to actually see the entrance to the State House.
