Yeah, sure buddy, I'll do just that... I'll keep walking until no one can hear me scream... and then a darn bear will come out of the brush and have me for lunch!
You think that you don't get out in the woods too often... after all unprovoked attacks by bears are just hugely thinning human populations.
I've walked in the appalachians my entire life, and I think maybe a handful of times in my entire life I have actually just stumbling across a bear without trying to find one... and never was it at a close distance. But if you feel better, or insecure in your ability to deal with the that threat carry a gun with you.
I'd be more worried about Mt. Lions if I lived where they reside than I would bear. They definately will predate a human if they get a chance.
Bear's generally not going to view you as lunch, unless there is one hell of a food shortage going on. Feeling the wrath of a mother bear who is protecting her cubs perhaps... but unless you are out there like that nut job up in alaska trying to get close to grizzlies.... I wouldn't be losing sleep over bears hunting me down as a food source.
