Watching what they do here freaks me out. My father-in-law used to be a truck driver. I'm watching and wondering how they will accomplish it, but they do. It's amazing.
We met 3 tractor trailers, one a double trailer on a switch back similar to that in Utah a few years ago. The truckers were very skilled and our driver, Kenny Brabant did a great job. I can only take credit for not breaking the bones in Leo's hand from holding it so tight and not screaming!
The video below is Amazing! Even more amazing is the cooperation between all of the motorists.
