Good evening, yarddog...is that a bulldozer in the ditch or going into the ditch to rescue a truck?
I think that is a truck in the foreground. I have no idea what the dozer/tractor combo is doing. Maybe going to pull the truck back upright.
One thing they did which seems impossible to me is they assembled and installed a foot bridge across a river. The part that was hard to believe is they built the bridge six inches under the water and at night.
