Sgt. Allemane, your code phrase for the Master Terminal is "Smoker Boy." Yes, I'm telling you to kick the habit. Don't you got enough nasty going into your lungs?
Before the Wastelanders update, Allemane's corpse, and thus this note, was found beside a large orange crate near the gate to the Big Bend Tunnel interior. When the Blue Ridge outpost was added with Wastelanders, Allemane's corpse was moved to be outside of the outpost, on the rocks near a train car.
