Ex's in reverse? Could have been easier on the Op's to pull back on the travel sticks or mash back on the pedals rather than push forward for such a distance. Can't say for certain but I would have found that easier on the old hip-down appendages. As for the dozers, as some other's have mentioned with the cables over the blade it afforded some lift which I'm sure was required since they were "lubricating" the ground with water or -wait for it- some super slick, top secret earth slime.
I liked the video and thought the guitar work was darn decent as well, me pick-on the fiddle too.
Thanks for sharing...
