Dual Survival

First you've got Dave Canterbury.  He's your basic military-type guy.  Then you've got Cody Lundin.  He's your naturalist-type guy.  What do the might-makes-right man and the tree hugger have in common?  Well, they agree on a few basic rules of survival but outside of that, very little.  This show puts the two men together and forces them to survive in several different places.  Will they live?  Will the elements kill them?  Will they kill each other?  Will the elements mostly kill them and then they finish each other off (or vice versa)? We really doubt those last few things will happen, but hey, who knows.
