"We had some fine video of some 1200 gallon sprayer tanks blasting through a gate, and a large toolbar being pushed across the road by the wind."

I believe it. My dad had an empty liquid fertilizer tank in the field (waiting to be picked up by the dealer), when one of those big winds hit our parts of the province (Assiniboia area). That tank flew through the air like a big balloon, nearly smashing into a neighbour trying to drive her truck to rescue her husband from where he was working. The tank finally came to rest miles away from where it started.

I'm sure I would have shat myself, had I seen a tank that big flying towards my little truck. *gasp*
