With all the lions, tigers, bears, crackheads, zombies, yeti's that are mentioned on this site in conjunction with guns.....I'm left wondering if many here just aren't really mentally prepared/experienced enough for backcountry travel. It isn't for everyone, and many here come across sounding like they just don't feel comfortable out there. The best way to know if it's important or not, is to spend enough time in the sticks without one and you'll know.
If you are an experienced outdoors person, your answer to yourself and your partner should be simple. From your question, I'm assuming you've never needed it in the past.............? So, what's been your experience.
Most of my friends and I have spent our lifetimes outdoors.....climbing, backpacking, flyfishing, hunting, etc. None of us even remotely feels it necessary to pack a gun during backcountry travel inthe contiguous states. Here are a few exceptions we make.....one, is while hunting (no-brainer). Second, is when on our Alaskan fishing trips, and we leave that business to the guides. Truth is, individually we've had many encounters, primarily with Black Bears, and cats. Most of those encountered amounted to views of them desperately running in the opposite direction to avoid contact with us.
Most of the wildlife attacks in North America are resultant from human stupidity. If you leave the gun at home and bring your brain with you, you'll be just fine. As for human interactions, I would venture a guess that there are far more crimes and opportunities to become a victim of a crime occurring daily within a mile of your home than will ever be realized in the boonies.
