I never hike or camp alone. If not with anyone else, I always have either Smith&Wesson or Mr. Glock or Mr. Ruger with me, all are close long-time friends who've been with me through much adversity. In fact, at least one of them is with me even when I'm with other people.
I've been hunting, hiking and camping in the wilds most of my life, and most often alone. For years I worked in a law enforcement job where I was alone and if I called for help on the radio it would take many hours for help to get there. I don't fear when I'm out alone, but I'm not stupid, either. I prep as best I can, and let reliable people know where I'm going and when I'll return, and all that other stuff so often preached. Then, I take what comes, and try to do the best I can in whatever the circumstances may be. I find it liberating and enjoyable.
However, I don't like it. Any outdoors experience is much more enjoyable when shared with family or good friends. I greatly prefer to go with another person, maybe two, but if no one is available to go with me, I'll go alone.
