As we were taught in Alaska, Keep two cans of STERNO and matches in the car. Keep hard candy on hand, blankets and flashlight.
My thoughts, add two plumber’s candles to the list.
Yep ......we have a few of the 8 day candles that fit perfectly in metal coffee can style “heaters” we made for each vehicles emergency kit. Work great .
Fuel gel from my fake fireplace wouldn’t be a bad idea either.
