How many people travel every year in the frigid cold? Millions, right? How many travel via remote areas where if they broke down receiving help would not be the easiest thing? Lots of people.
I remember a story several years ago where a couple took a wrong turn in the mountains – no cell phone signal and their car got stuck in snow. The husband ended up going for help and died while succumbing to freezing temperatures. The wife was eventually rescued when they were found to be long overdue to their destination.
I own two of them and stock up on small propane canisters all Spring and Summer.
