The Limit Is How Far Can I Walk

I've gotten the impression that there might be a limit. But what I've seen weather wise is the limit is how far you can get from your shelter, getting up before dawn and get back no matter how bad the weather gets. There are no trails. Landmarks are confusing. If you wandered too far from the shelter and you couldn't get back, you'd have to request to be an emergency extract. They couldn't get out and they couldn't get there with the chopper. Dude had to find a way completely on his own with no shelter or help to get through a night below zero. Wow. So your limit is howfar you can walk because there's nowhere to go
