Lately they have been using Brine around the NY, NJ area.
I've heard that but brine is just water and salt. Not sure what the
advantage of that when it's too cold for salt to work at all.

Can't say what type of salt they've been using, but here in Toronto
it's been as cold as -30°F lately and it does work as long as the snow
is not excessively deep.
