I really did not relish the route, on the green line, I took when I was going to a crappy language school, but I did enjoy looking around while taking the subway as part of it runs as a trolley. This lent itself to exploring new places. One of them is the Boston University central campus, seen here. The Martin Luther King Jr. sculpture was truly appealing for those who are keen for art. I wish I could have seen it when the sunlight creates the shadow which appears on the ground. There is always next time.
