The only two shows I remember stage dooring for at MTC Stage I are Ruined and The Receptionist, and I think that in both cases, all of the actors exited the building through the same doors that the audience does. So I would wait on that street for the actors. If you wait inside, you might miss anyone who gets to the exit level by using the elevator (which a couple of the actors used), unless you are really fast and alert. (Of course, if it's freezing outside, it might be worth the risk!)

"you can't run away forever...but there's nothing wrong with getting a good head start"
"well I hope and I pray, that maybe someday, you'll walk in the room with my heart"
