Killing Time is a holodisk found in Fallout 3 on a corpse to the south of the hilltop farm ruins, north of Canterbury Commons. The corpse is that of a generic wastelander (the BaseID of this wastelander is 6558A and her RefID is 65593). The note serves no tangible purpose.
I don't know how much longer I can hold on. I'm pretty sure I broke my leg about two miles back, and now I can barely limp forward. So here I sit, writing this stupid journal.
Oh, and someone's been tracking me. They've been watching me for about an hour now. I'm hoping they're friendly. Guess I'll find out soon enough.
