We just got across a video that made a question pop up in our minds: are snowmobiles more fun than dirt bikes? They must be if ridden by the craziest guys in Iceland, just as this video reveals. It shows two guys worming up their sleds into a local reservoir and then deciding to climb onto the extremely steep concrete walls, the first up the side of a 30-foot cliff and the second goes for a mind-blowing 70-foot one. You’ll need a breath of fresh air after seeing this and start looking at snowmobiles as to gravity-defying machines. I guess this does make them better than dirt bikes.
