I usually end up on my own ( not by my own choice, people seem to be flaky about cold and wet ) with the exception of my 357 being at my side. I am always looking to work with others out this way but it seems pretty empty of folks who want to work as a group or commit the level of time that I do.
It can be very dangerous and go very wrong very fast. Cougar populations are on the rise and in knowing that I always like to either be on the high ground or watch any rise I may be passing by. You should evaluate every location you move through from a predatory mindset and avoid ledges or rock outcroppings near pinch points. I am not so worried about bears, they seem to lift feet when people come bush battling through. I also entirely avoid red or pink colored accents on my clothing.
I also always carry a small med kit, compass, strong blade, multi-tool, 100 feet of paracord, 2 mylar blankets, pocket survival guide, painters drop cloth ( great shelter waterproofing ), gorilla tape, fishing kit, 6 fire starters, a flint striker, lighter headlamp, spare batteries, water filter, 2500 extra in carb calories and a good sized bag of common sense. If you have these things and know how to use them then you can make it back to civilization almost every time.
