I'd no more head out into the boonies without a rifle than I would without provisions, water, extra fuel, etc.
I'll share an experience I had a couple years ago where the presence of a firearm (on my part) brought a situation to peaceful conclusion that otherwise might have gone very badly for everyone involved.
This took place at a campground, somewhat off the beaten path out in the boonies, hours from the nearest emergency services and way out of cel range. There were a few other campers around, so we'd set up in a spot a distance away from other campers so as not to disturb anyone. It was after dark, and I was getting ready to bed down (my wife and young son were already in bed), my dog was leashed to a camp chair and I was cleaning up camp just after dark when I heard voices heading our way immediately followed by a couple of bocce balls coming into our camp, one nearly hitting my dog. I looked toward the voices and direction the balls came from and saw three guys headed our way like they owned the world. There was plenty of space on all sides of us, so there wasn't any good reason for them to be near our camp other than they wanted to be there. As they approached within 50 feet or so the dog started a low growl, and I politely asked them if they wouldn't mind taking there game to a part of the campground that wasn't occupied and rolled their bocce balls back their direction with my foot. One immediately started yelling at me with attitude called me an ******* with poor sportsmanship and that maybe I needed to shut up. I responded that I was merely asking them to respect the boundaries of my camp site and there was plenty of room for everyone, so if they wouldn't mind simply taking there game to an open part of the campground, I'd appreciate it. Then one of the wingmen started in on me with something about a "lesson" (all the while they were steadily approaching and about 25 feet from me). I decided at that point that since their errant bocce balls were within their reach, the dog was growling at them and they were still coming, it was their intention to do me (or my family) some 3 vs 1 harm and if they continued to pursue this course of action and came inside the boundary of my site I would be forced to draw my sidearm to address the situation before they got close enough to get hands on me (or worse, get my family involved). At this point, I was on full alert and my demeanor had shifted from polite to ready to engage. I faced them square on and told them in clear, calm voice loud enough to be heard at a distance (so that if I was forced to engage, my warning would be heard by other campers) to please stay out of my campsite and leave us alone. The first guy started running his mouth again and continued moving toward me when I saw number three look directly at my holstered side arm (I don't think they realized I was armed until they got close), look me in the face and then grab mr. mouth, telling him that they should just take their game to the other end of the campground. Three said something to mr. mouth that I couldn't hear, but it shut him up and all three were suddenly very polite, immediately moving away saying "Sorry for disturbing you", picked up their balls and left. I stayed up for a while after keeping an eye out and thinking about how close I'd come to having to point a firearm at another person and my resolve in doing whatever had to be done to ensure the safety of my family and myself. Thankfully, that was the last I saw of them.
At no time did I raise my voice (aside from the last warning), lay a hand on my sidearm or indicate that I was going to do anything but stand there and talk. I am 100% certain that if I hadn't been armed, the outcome would have been less peaceful and given the odds of three younger combatants vs myself (or my wife and child). An interesting point is that none of the three qualified as what I'd call a "Shifty looking" character. If they'd been nice, they'd have fit right into the "normal person" mold.
Obviously, this is not a typical scenario but it does demonstrate that not everyone you meet wants to be your friend and help isn't always a 911 call away. I look at carrying firearms as an insurance policy against exactly this kind of thing. There's no way to predict when you might need such a policy (hopefully never) or be entirely on your own to resolve a situation where the odds are stacked against you. Having every tool available to increase your odds is simply being prepared and prudent.
