I've live in both the North and the South. I've slipped on the sand and kitty liter when the ice doesn't melt enough to take hold. I will grant you that it works well on SNOW if it doesn't have an ice layer underneath. But I've seen sand used in the South do nothing but give an illusion of traction. It is entirely different than salt used up north that actually melts ice. (and ruins cars)
