Funny, here in Alaska we don't use salt. Lots of sand and plenty of plowing. When I lived in Mi., I thought salt was the only way to keep the snow off the road, that's not true, it is just the least expensive for DOT in that area. Here... we don't have a lot of salt at our disposal but we have a lot of sand. Even funnier to me, I grew up in Ca. and didn't know snowplows even existed back then.
