Winter is predicted to be a harsh one again this year. If it snows so badly again then this year will be the first time I've owned a car in such conditions. I want to make sure I'm prepared as I can be for it because I have quite a commute to work on one of the county's most dangerous roads. What essential bits and bobs should I be keeping in my car in case of snow related emergency? Snow shovel? Wheel Chains? Flashlight? etc?
