Something I was never able to get my head wrapped around is how anyone could actually believe they could make a "treck" from Northern Alaska to Southern Argentina and stay off road 80% of the time. Imagine trying to do so just in Texas, let alone everywhere else.
Over the years I've been over just about that whole Alaska to Argentina route and I can say that you would either end up robbed and bleeding along the road, in jail for tresspassing, shot dead by a farmer for tresspassing or snake bit from attempting to stretch a cable.
Be it in Alaska, Alberta, Texas, Mexico, Costa Rica, Columbia, Equador, Peru, Bolivia or Argentina. Somewhere, a property owner is going to take issue with having ruts acress their fields, fences knocked down etc.!
I've been in places in Equador and Peru where I didn't want to get out of the vehicle let alone step off the road. The Amazon is not a place where you want to streth a cable.
I've always been amazed how such a hair-brained fantasy coming from an educated man.
Beam me up Scotty
