Enter the Snow Extrication Kit. Most people who live where there is winter tend to carry a shovel, probably a bag of kitty litter, and ideally a flashlight and a blanket, just in case. This puts several things together in one neat package that doesn't take up a lot of room, but could actually save your life someday. It comes with not only a metal-edged shovel for digging your way out, but an industrial ice scraper and swiveling snow brush for making sure your windows are clear when you do get to go somewhere. The piece de resistance, however, is the grip track, which you can place under your tires when they're just spinning uselessly in place to get yourself moving again. It weighs a lot less than a bag of kitty litter, and is also more effective. The grip track measures almost three feet long, and is constructed of stainless steel cables with independent rubber treads.
The best part about this is it doesn't take up much room in your trunk, and also weighs almost nothing (all of 11 pounds). The shovel handle triples its usefulness by being able to be used with the ice scraper and snow brush. Everything fits in a neat little briefcase-type bag with a convenient carrying handle. What I find neat is the grip track can be used in all seasons, in case you get stuck in sand at the beach or something.
If you want one of these kits to ease your winter concerns, you can pick one up for about $70.00 US.
