Correct me if I'm wrong but usually Spider-Man is seen in New York City. He is from Queens after all. Yesterday was an exception and Spidey was hanging around in Boston, MA. Apparently he ran out of webbing because he resorted to taking the T to get around the city.
Now I can't blame Spidey for being in Bean Town. It's a favorite place of mine to visit. The Celtics are currently red hot in the Eastern Conference Finals. Perhaps he was craving some New England Clam Chowder?
I just hope he foiled the plot of whatever enemy he was going up against.
