Just to clarify the converstion, what exactly is a "wood's gun"? What is in the "woods" to require a firearm to deal with?
I'm with you on the snake part. Long stick is all you ever need. But....
In VA, you are probably right that 2-legged is your biggest potential adversary.
I have hiked & camped in the wilderness all my life, almost always without a firearm. Given the risks out there, having a gun was low on my list of priorities, especially considering the weight.
However, there *are* instances of serial killers specifically targeting hikers. It's not unheard-of. So when Kel-Tec came out with its P3AT, which weighs next to nothing, I started carrying it on occasion.
The next thing is bears. It's endless entertainment - like sharks - but again, low down on the dangers while hiking. But not zero. I have had a bear harass me aggressively once, in the Huerfano valley in Colorado. Pretty remote place. Turns out that's where CO sends its problem bears. Gee thanks. It would have been nice to have something besides rocks and pine cones to throw at it when it started growling at me.
Pepper spray is probably your first defense, if you are going to carry anything, but I see nothing wrong with having lethal force handy as well, especially when I'm hiking with small kids.
Grizzlies and brown bears are a different matter. They DO hunt people, on occasion. Anybody who spends enough time in the woods in the West will eventually find him or herself in grizzly country.
Polar bears really, really do hunt people, not just on occasion, but fairly regularly from what I know. But that's outside most people's experience. Mine certainly.
I grew up in a fairly hippy-dippy family, the kind that would probably poke fun of people taking guns into the woods. Especially in black bear country, I'm not *afraid* of going on long solo multi-day hikes in the wilderness, sleeping in nothing but the hollow of a tree, without a firearm or pepper spray on me, let alone satellite phone. I do it all the time. But, I also have no problem with bringing a gun with me, either, for protection from both 2-legged and 4-legged animals. Despite what you may hear from other people who like to go on about statistics of lightning vs hypothermia vs everything else, it is, frankly, not remotely a crazy idea. People do, in fact, get killed while hiking/camping either by other people or by critters. It does happen.
P.S./Edit: Other than people and bears, there's also feral pigs. The feral pigs in East Texas backwoods are on occasion aggressive enough that, if you are on the old/infirm side, you are unwise to walk in the deep woods without either a gun or a very large and protective dog. The pig population has actually exploded across the country in fact, for reasons that nobody knows.
As for cats though, personally I don't worry about them at all unless bowhunting in which case they are a potential threat when I return to my carcass to carry out the next load of meat. Big kitty-kats can be rather protective of a kill site.
