I think it’s highly depend not on how cold the climate is. Do you know the specific location? I see you’ve listed a few.
Anecdotally, I grew up in a suburban area southern Michigan where the winters could get brutally cold and there is a lot of lake effect snow. But I never needed to use an engine block heater or special tires. Read wheel drive vehicles were ill advised for winter months though from what people had told me living there. I had a small FWD crossover SUV for the bulk of my time living there and it was fine. If you have to drive in snow and icy conditions, go very very slow and bear in mind that you cannot stop, accelerate, or turn quickly at all.
The most essential think I needed was an ice scraper and remembering to warm up the car first.
Obviously ymmv depending on how cold your location is and whether or not you’re living out in a rural area. Also where I lived was likely a tad less cold than Denver. But cars were generally still able to start at -5F for reference.
It’s interesting because this has to be pretty conflicting for that man.
I mean, yes you do have memories at 6 as an adult…but really not many. I know he knew he was taken away from his family. But it says that they kidnapper interestingly raised him to being an adult. I wonder what that relationship between him and his kidnapper was like and if he felt that she had become his adopted mom or not.
Shame his real mother never got to learn that he was alive and well. I’m sure everyone assumed he died…as is what happens to most children who go missing.
