My husband and I are planning our first trip to Boston. I have never been further north than Tennessee so I am very excited and very nervous. I have no idea what to prepare for, so if you could please give me some tips. We are flying in and getting a hotel. I read that it would be better to take public transportation than to rent a car. We want to be able to explore the city's history and everything else it has to offer but with some sort of preparation. I don't want to be lost all the time and confused. I really want to enjoy Boston. Thanks in advance.
