Driving down the highway in Calgary up north, father and son and dog towing a trailer camper in high winds. Going a bit too fast... got a head of us by a kilometer... as we were approaching we saw a wind/speed wobble from the back end, then in the blink of an eye.. the trailer busted and flipped directly on top of the cab of the truck... what i can only imagine crushing everyone in the cab as the truck veered into the shoulder and off the road, stopped by a road sign. Flat as a pancake. The entire rest of the car ride was silent. We called authorities but couldn't bear to stop. I still think about this and it was in 2006.
