Replying to Cool places to go?

hey, me and my friend want to hang out tonight and smoke some green... we just need a place to go since we both live with our parents (16 years old). what are some good places to go that you can think of to go to(close to boton and west of boston if you know that area)?

we were thinking:
-the mall, and tell my parents we might go and see a movie since the theater is right there
-the movies (probably will fall asleep though)
-moody street (like newberry street on a much smaller scale in the town over from ours)

what are some other good places we could go tonight?
