those 2 shows are right there with man vs. wild,though bear grilles is a bit nasty compared to those guys,i mean come on who drinks water from elephant feces?*shudder*
though i think they'd get more inspiration from the tv show Jeremiah since it's actually a post apocalyptic tv show. maybe even from the "reality",and i use the term reality very loosely since there's absolutely nothing real about reality shows,show the colony .
