We arrived in Boston last night and spent the evening downtown. It all started with public transportation.... We went to buy our ticket for the week before heading downtown and this guys who had followed us in the building started asking for money. We all said no. One of our group members was given a ticket that worked for a few days and gave this to him, thinking it would rid us of him. Our group continued getting passes for the week and he hung around. When we got on the train, he did to (Did I mention he was wearing sunglasses the whole time, at night?). He seemed to stalk one girl in our group, asking questions and making comments. Then he followed us to where we got off. We also noticed him signaling another passenger, who looked shady. This was our first experience... it made us a little nervous to walk alone in the park that we have to go through to get to our hotel, but it's been all good since.
