Added more warmth to my EDC purse: chem hand warmers, extra Heat Sheets blanket, hat, mitts, food, etc...

I also added some plastic bread bags. They're light and small, and they make a great protection from soakers in the cold and wet.

Lock de-icer is on my shopping list now, along with a small ice scraper. I also need a new head lamp for my purse. (Mine was recently broken by my 4 year old.) Hands-free light is crucial sometimes.
