Hell, we got a Marine with us!
Hey iShred, can you borrow a tank?
Even if you're fortunate and avoid any of the very real dangers along the way, driving from one end of Latin America to the other pretty much guarantees one thing: someone's going to get sick along the way. (Don't forget it will be winter in South America.) I've had Montezuma's Revenge in Mexico and the flu in Bolivia -- no fun at all.
