I've always thought this is one of the more beautiful streets in Boston. For those who don't know, it has a park running down the middle that is full of trees, benches and statuary. The houses on either side are town houses, row after crenellated row. The fronts follow a pattern of advancing and recessing rooms in regular order.
I walked the South End linear park between the Mass Ave T station and Back Bay station. It's a nice winding, leafy route and while the brick townhouses along it aren't the best examples of South End charm, they is nothing wrong with the atmosphere. At Back Bay station, we cut over to Commonwealth Ave, through Copley Square in front of the Library, and hit Commonwealth where the firefighters' memorial is.
Quiz: What would the park in the middle of Commonwealth Avenue be called in New Orleans?
A: Neutral Ground.
