Full version of the D11R pushing a massive rock.

Nice. Reminds me of when I use to live in Colorado. It was 1978 and road construction was going on as I made my way up to Estes Park. A dry river bed next to this road had a bulldozer in it pushing a boulder at least 20 times the size of the one in this video. The bulldozer was so big it had a long climbing ladder to get to the operators cab and every time the boulder would flop on it side as it rolled along, I could feel the shaking on the road and hear the rumble. Too damn bad I had no way to film it. The rock was as big as my 2 story house!! Couldn't help but stare at the awesome scene. The bulldozer was not even working heavily. The boulder was mostly round, that helped.  U could tell that it is quite old from the rattling and shrieking sounds and yet look at it's display of such enormous power - I was comparing the size of the rocks to the operator in the dozer. lol
