Professor Hike (a.k.a. Jason Stevenson) has a thoughtful article on the Backpacker Magazine website regarding the things that hikers fear the most.
He makes the point that many hikers spend far too much time and energy worrying about scary — but low percentage — threats like bears, cougars, and poisonous snakes, and not enough time concerning themselves with dull but common dangers like germs, blisters, and hypothermia.
I agree with him for the most part, but hiking in grizzly country still makes me uncomfortable. I once saw a grizzly on a trail in Yellowstone. That glare he gave both my wife and I was quite frightening. Fortunately there were a couple of other hikers in the vicinity at that exact same moment, so the bear didn't bother us.
For those that find themselves worrying about any or all of these low percentage threats, hopefully this article will help tyo keep things in perspective the next time you hit the trail.
