Some folks aren't prepared to spend the night in the woods if badness happens to them. I didn't when I was younger, but I read Horace Kephart's book Camping and Woodcraft, plus heard some horror stories, so changed my ways....
OK great, so you know where you are, but it's sundown and you really FUBAR'd your back when you started dragging your deer so you can't walk or crawl to your vehicle. You weren't really hunting alone, but your hunting buddy had a firearm problem so left really early, and urged you to stay and keep hunting and you thought "Gee what could happen?" You have no idea why your cell phone won't get a signal..., solar flare, an odd place in the woods, or some snot nosed teenage hacker has messed with your cellular provider's system... doesn't matter..., you can't call for help. Your buddy forgets to call to see if you made it home with a deer, and you forgot to tell somebody where you were going OR maybe you live alone and there was nobody to tell....,
This is not a far fetched scenario. I may not have a nice night, but when I go afield I have enough to go through a night if badness happens, and that's just when I am "local". Farther afield I'd probably look to most people like an armed camper, not a hunter who might be on an extended trek...
There is a reason the Boy Scout motto is Be Prepared
