i was thinking the same thing about tread lightly lol...... but it did seem they were on a trail "most" of the time, and even when there was "no trail" at the glacier he seemed to back down what looked like a road lol....

And ta tell yea the truth, alot of the videos i see of 4wds in alaska shows them in the rivers, tearing up brush, etc etc etc... that doesnt mean that its ok to do, but it may not be illegal up there to do what they did on the show...
