1. Snow/Ice Scraper: Especially if you park outside!
2. Blanket: When you're freezing or a random football game.
3. Salt: To melt ice off your car (probably special ice melt that doesn't damage paint.)
4. Lotion: Hello dry skin.
5+6+7 Inexpensive Hat/Gloves/Scarf:Pick these up from Old Navy or Target and just have them in case you get stuck waiting somewhere.
8. Old Sweatshirt: It's post party and you're freezing in your LBD. Toss one on to drive home.
What do you keep in the car during winter?
