I didn't get to see the post either.
I can see where salt on our cars could be a MINOR problem.
In the seventies I used to drive across the flats 8 to 10 times a month. At that time there was white salt all the way out to the 36 mile post. This year, driving west, it was still dirty salt, not white, at the rest area.
At the chemical plant (whoever owned it) would be numerous gondola train cars loaded with salt to be shipped to who knows where. One train of which there were many, would have more salt on it than we have carried off on our vehicles since salt racing began. Some years when the salt is good, there is almost no salt leaving on the cars and trucks.
When they started racing on the salt, it is said the salt was 48" thick, now it's 1/2"
The laws of physics says it can't just disappear, it has to go somewhere. My maybe misplaced logic says over the years approximately 46" worth of Bonneville salt has been shipped away for profit, all the while, being denied by the chemical company and the politicians let it happen for contributions.
Rant over.
