Site-Seeing in Boston on my own

While out in Boston, I took the commuter rail to go Downtown. I attempted at following the freedom Trail, but I suppose I was having many a "blonde moment" and therefore walked around town completely by memory and found all the sites. I think that doing it that way really made the day more interesting, and made me feel like I was a local just walking around making the most of a sunny Boston day. Without a map and refusing to look at Google Maps on my Blackberry, I just walked around and found all the sites. Boston really is such a great city, with all its public transportation and rich history.
