With the afternoon open we grabbed a train and headed towards Harvard. There was a tour starting at 2 pm and signed up when we go there. We waited….and we waited and unfortunately we were told that the tour guide (who is a student) was going to make it due to mid-term exams. But, the good news is another guide would be there for a 3 pm tour and we were welcome to take that one. I would say that the Harvard Tour for me was the highlight of the trip.
