This is my first winter at FedEx. The guys with experience told me to keep a bag packed in my car to take with me in case I get stranded. In my bag I have A blanket Gloves Socks Underwear Canned food with a spoon Nature valley bars In my cooler I have bottled water and my lunch for that day. I also have a credit card just in case i get stuck at a hotel outside of the network. Am I missing anything?
