Mag chloride sucks.
I lived in Colorado for awhile (Longmont/Boulder area), and at that time it was strictly cinder alone that was used. It had a tendency to make a vehicle look pretty bad, and I suppose it was an old school way of doing things, but for the most part it helped provide traction and didn't result in rusted-out body panels, so IMO it wasn't the worst method ever devised.
