Thats nice to know..I'll stick with the rock salt/ ice melt..if I get out the side door of the van, and see ice in my path, I grab the salt and throw it by hand in my path on those unmaintained Flying Pilot areas..smh..I'm not risking falling on my plump behind.No. But it will give you instant traction if you're stuck. Just a handful or two under each drive tire and you're good to go.
I carried a gallon container of kitty litter with me every winter, and only had to use it a couple of times, but was really glad I had it when I needed it.
