Looking at train schedule. Looks like the last train from Boston to Newburyport leaves Boston at 10:20 pm. My guess is that is too close to the end of fireworks to really make it. (Please correct me if wrong). Don't want to be driving in Boston, so thinking about parking on T stop and riding in. If we do that, where should we park and ride, realizing we will be coming from and going to Newburyport.
