Which door did Booth enter?

[Laurie Verge]

Unless someone was timing Booth's every move, there is no way we can ascertain how much time he spent in the theater before the murder or truly how long it took to leap from the box and run out the back door.

Anyone who has seen the layout of the theater and been backstage (such as at least Jim Garrett and I) knows that a man could hobble that distance in under a minute - even with a broken leg. There is not much space behind the stage, as several of us found out while waiting in the wings to speak at one of the symposiums they used to hold.
