The "cat's cradle" technique is very rarely seen due to the lack of anchor points for snatch blocks near highways. It really comes into its own when a heavy vehicle sinks, or rolls over, in a forest.

Wow, very impressive. I like how they said they tried pushing it out with a 'dozer and that did not work, and then later in the video you can see the back of the truck with big letters "DO NOT PUSH". LOL :smile:
