You should have seen what I kept behind my seat in my pickup when I lived in rural Wisconsin.
I kept enough gear to keep two people alive and fairly comfortable for 3 days, figured on temperatures of minus 10 to minus 20 degrees. and heavy clothing and boots and socks to walk out with.
In Minneapolis I ran out of gas one day in that truck at about temp 0 and when I started walking for gas I realized that I was wearing blue jeans and cloth tennis shoes, luckily I was in the urban area so no frost bite happened but it made me aware of how many people in that region jump into their nice cars unaware of what would happen if they had to spend a night in the car, or walk two hours for assistance in 20 degrees below zero.
Yeah, I’ve been in some pretty nasty storms here. I believe I will start working on getting items into the trunk of each car. Thanks for the tips.
