I'm getting the idea that winter is a real PIA for you guys!
I keep granola bars, T-lights, stowaway shovel, glo sticks, blankets, sleeping bag,flashlight, mitts, scarf, extra coat, medical kit ( for your use or someone else’s) If I’m travelling out for the day ( in the winter) I always carry a 24 hr supply of dog kibble. ( if I’ve got my dogs) a friend had to detour once, avalanche and rock slide inadvertently sent her to a hotel for the night with her dogs. She had no food for them.What do you keep in your car during a snowy winter?
I have kept blankets in the car, and usually add boots if I wear shoes. Not sure what else I should include.
I'm always turned off by long lists of items of things I won't use. My most likely situation is a minor car accident and waiting for sheriff/tow truck, or getting stuck in a ditch and either waiting for help or walking a couple miles.
