Here in New Mexico dust devils are no joke. I got hit by one while riding a relatively heavy motorcycle, and I was lucky to stay upright. One other time I saw one loft a 45 gallon plastic trash can 60 feet. One upended a wooden shed at a ranch where I worked.
Those dust devils toss kids playing in those inflatable castles and such way up into the air and kill many more kids than one would expect. Those things are dangerous especially if there is any wind at all. A five year old got killed in Maryland and a 2 year old got killed in Arizona recently.
You aren't kidding. About two weeks ago, a guy sitting on his motorcycle behind my wife at a traffic light was knocked off his bike by one of them. A second guy in a car right behind him jumped out to help him pick it up. My wife said the motorcyclist looked stunned.
We used to joke that the F- rating of a dust devil was determined by how many Walmart bags were swirling around in it.
I guess it caught on, because at one point radio host Jim Villanucci repeated the joke on-air.
