In New Mexico, we used to identify the “F” rating of a dust devil by the number of Walmart plastic bags swirling around in the cyclone. 1 bag = F1, and so on.
If the bags are banned, an important meteorological tool will be lost to us.
I always used the small child trapped in a tumbleweed scale myself. And for judging rainfall, the speed at which a homeless person clutching a mattress traveled down the arroyo.
