After finishing the business I had downtown, I saw a sightseeing trolley go by and recalled that I had never taken one of these tours on previous visits. I hopped on the next one, a CityView Trolley, and spent well over an hour enthralled by the driver's knowledge of the City and its history! We passed by many places that I had visited on my own on previous trips, but was amazed to get so many details of their significance and historical value as I got from our driver! It was an educational experience for me; and, with the combination of his droll wit, was very lively and entertaining. Highly recommend that this be one of your first activities when visiting Boston.
