This reminds me of Stephens Kings' "The Girl Who Loved Tom Gordon".  A 10 year old girl hiking with her family in Maine steps off the trail to take a pee...loses her way back to the trail and is lost.  She listens to Yankees games on her little radio, listening for her hero Tom Gordon.  But this girl made every effort to keep walking in a straight line, west.  And of course, King throws in a few weird encounters to make you hold your breath...
