I don't understand the salt ban in Colorado. Salt works fine back East. But a side effect is that you have a fair number of fine old classic cars on the road, much more than I see in the Northeast, that haven't rusted out.
A relative of mine drives a plow, so I'm not attacking snowplow drivers, who live a rough life during times like this.
I didn't get the feeling that you were attacking plow drivers, I just wanted to help educate people that may not know the circumstances involved. Many enviro-whackos, when informed of the consequences of their movement, rethink their positions. Well OK not many, but a couple of the ones with critical thinking skills.
I believe the Canadian province of Alberta implemented a salt ban some years ago to reduce the number of vehicle-animal collisions in the winter time. Apparently deer and elk would congregate on roads in the winter to eat the salt.
Kills roadside trees.
A number of years ago, Colorado switched from salt to magnesium chloride. Truck drivers don't like it, because they said it's causing corrosion to the wiring and brakes on their trucks.
