Honestly, my first thought seeing the original post was "how do they know where to go?"^^^^ this is a job where a very accurate GPS comes in handy !
This is very similar to what they do to open up the Going to the sun road and the Bear tooth pass .
That better be one super accurate GPS! I can't even stay on the gravel when I plow my driveway, I always end up drifting out onto the grass in a few places.
