We met our very knowledgeable guide, Michael, at the Boston Common, after having bought our tickets online at Freedomtrail.com. This was especially convenient because the tickets were usable for any scheduled tour, so lots of flexibility there. Our guide was quick to point out that he was a teacher at a local college, ad not an actor. Lucky us!! Michael was full of facts and dry wit and the freedom trail tour was a wonderful way to see a lot in an easy way. We finished off at the USS Constitution ship, and then took the ferry back to the city.
