A couple of things about Boston Geography:
Beacon Street is a few streets north of Copley Square. Copley is directly bordered by Boylston. I'm also fairly certain that there's no Rainbow St. anywhere near boston.
Also, another slice of trivia:
The last friday of every month Copley Square is the gathering point for
Critical Mass. Critical Mass is a lot of fun.
