I'll be staying in the North End for a few days and was looking for an interesting trip for my family. I've heard that the green line is neat, but I'm not sure if there's anywhere that we'd want to stop and get off to explore. I have a three year old who hasn't ridden these kinds of trains before, but I want to coordinate the excursion with a nice lunch stop or something similar.
You guys have been super helpful so far, I hope you have some great suggestions. We like libraries, historic buildings, and funky/quirky places to eat or walk around.
