A lot of trucks come to grief on the Ingraham Trail. Most victims of the trail just lose concentration or drive too fast. But there's a driving school in Yellowknife that puts its trucks on the ice road every year... heading back to Yellowknife one time, one of the drivers fell asleep and went straight off into the snow bank about 30ft. I so wish I'd taken a shot of a truck with '---- ----Driver Training' written all over it half way through the snow bank!
Get it badly wrong, and this is what happens.

New underpants, please! Buddy wasn't badly hurt. This is what happens when you get it wrong on one of those negative camber bends. Damn, this has to be scary. I wouldn't wish this on anybody. He probably just didn't clench his butt cheeks hard enough...
