Idiots.
Only one of them was driving. I guess well never know if the others complained about the speed.
I cant even imagine going 70 mph in a 15-passenger van down a dirt road headed for a bridge, and Ive done some pretty stupid things in a moving vehicle.
You have to see these roads; they look like unpaved interstates and carry eighteen-wheeler log trucks going like the hammers of hell. You go less than 70 at your own risk.
