If this guy really wants to do this (and isnt just doing it for $$$ and to get a website), I don't think he knows how far he'll be walking. It's 3000+ miles, 60+ hours worth of driving time (if going 50 mph constantly). Lets do a little math: if he walks an average of 2 MPH, that's 1500 hours of walking (62.5 days) and that's not counting time that this fat fuck will need to eat, shit, and sleep. Ambitious, but insane.
edit: I just read the journal. He's been going for almost 2 months, and hasnt made it out of California. It's gonna be a longggg mission
