“I don’t remember, really. It wasn’t like the kind of granularized stuff they used to use. Just some kind of liquid that had a lot of salt in it.”
I believe some places use sea water.
Salt, beet juice, chemicals.... none of that is going to work when it’s 12 degrees out (morning temp in Atlanta). The only thing that works below 20 degrees is sand, sawdust, etc. to provide traction.
