Since moving north a few years ago, I seem to get stuck in the snow at least once per winter. I'm really nervous about it. I'm thinking about getting a small foldable spade to keep in the car. A blanket (just in case). I've read that cat litter is good for providing traction but I'm not sure about it. Whether it's a good idea to carry a small bag of it. How much would I need? About a litre? Does anyone else carry anything just in case? I'm interested in hearing what others do.
