You guy´s seen this. http://www.youtube.com/watch?feature=player_embedded&v=wO3thZwQxUU
always remember there is always someone bigger than you!
This is an old video, saw this years ago. However if you haven't seen it before, it is worth viewing. Around here, a D8 is as big a dozer as we commonly see used. This video makes it look absolutely tiny.
