Track hasn't spent nearly as much time in wild places as he makes it sound like he has.
Don't get trapped by his bait...
Yup, anybody can spend 10 minutes in grizzly country without getting into too much trouble, particularly if avoidance is practiced, which by the way isn't the worst idea. But the more time spent on the ground in bear country, and the more bears that are encountered, the odds start to stack against you. We've played at attempting to figure how many bears we might cross paths with, before a nasty one is encountered, and every time we think we've figured it out, something happens to screw it up. We had 4 serious bear incidents here last year, where bears made contact with their victims, way over the norm, and in one incident, 2 people were seriously injured and had to be flown by air ambulance to Winnipeg. Those incidents occurred right in town, despite the daily patrols by both truck and helicopter, and despite the Polar Bear Alert Program which responds very quickly to reported sightings. Throughout the fall, all bears found within the zone throughout the fall season are either pushed across the river, or picked up. Yet despite all that effort, incidents still occur. One might surmise, that bear-human conflicts could also arise in the back country with a lone hunter or adventurer.
Attempting to adequately prepare for a problem, doesn't mean that you fear your environment. What it means is that you acknowledge that there is risk involved with spending time in wild places, and that you are taking steps to mitigate those risks. If you are in the back country on a specific mission, say you're sheep hunting, a bear encounter probably isn't even on your radar. But unless you think about this stuff beforehand, and unless you pre-program yourself to respond in a certain way, the chances of getting caught unprepared and being unable to react correctly, increases dramatically. This is particularly true if your natural reaction to a bear sighting is to close the distance for a better look, without considering the bear's personal space, which is known to be much larger for grizzlies, than for black bears, or polar bears.
If you choose to carry pepper spray, you should understand the circumstances where it can be used effectively, when it shouldn't be used, and you should have some idea of it's effective range. A shotgun is a great bear defense tool due to the great variety of shells, both lethal and less lethal, that can be fired through it. I prefer the shotgun option to bear spray, because with the shotgun, I can drive a bear away with a cracker shell before its close enough to injure me. The handgun, like bear spray, is only useful when the range is extremely close, but under those circumstances it trumps any other of the choices, particularly if the bear has already made contact, and you are injured. Hunters who carry rifles only, might consider equipping those rifles with iron sights and QD scope rings, or at least choose a scopes with a very low bottom end power; that is the only way it will be a viable close range weapon. Rifle, shotgun, handgun, and spray are all viable bear defense tools under certain conditions, and one should not be prevented by law from making his own choices, based on what he believes is the best tool to keep him safe. When arguments are made to the contrary, one must question the motives of the speaker.
