Why would you follow a GPS down a dirt road in the winter? In that area, it can be 50 miles to the nearest anything. The roads are rarely traveled and minimally maintained. Signs always say things like "No services" and "Roads not maintained". You just have to read. And you need a printed map and some actual knowledge of where you are going. GPS is an unreliable method of navigation without a map and sometimes with a map.
A few years back I was driving my vehicle that is modified for higher lift and beefier suspension on a very rough road in Arizona. Got through the section and was going to go the highway and go 40 miles back to the starting point that was about 6mi by rough dirt road. That 6mi took me 1hr . Here comes this guy and his wife in a Hyundai Sonata. I told him to go back to the highway. He insisted that the GPS said to go this way. I could not convince him otherwise even though my car was visibly more capable and covered in mud. The man and his wife were probably not capable of walking a few miles on rough terrain and in my opinion they were surely going to get stuck.
People rely way too much on technology and not on experience, common sense or even the experience of others.
