@lilwhiteboyz, maybe his feet hurt?
No but seriously, if you don't know how far and in what direction you have to go, it's better to preserve your energy and to set up a shelter for the night
@lilwhiteboyz, power lines can span large bodies of water or disappear underground. While it's not an officially approved method of getting help, it will work.
@CrazyManInaBox, long distance power lines can run through some pretty remote areas. But yeah, if he walked along the line he'd probably find civilization pretty quick.
Maybe follow them?
