Grayowl that was great, I can just see animal lovers that feel bears are just misunderstood, about filling their shorts. A black bear might try to avoid the bells or may be diverted by pepper spray (unless it's a sow with cubs), but for a grizzly it would be a dinner bell and the pepper spray would be like steak sauce. About the only defense, without an adequate weapon, for an encounter with an adult grizzly is to climb a tree as they have straight claws, but it better be a very stout tree because they can rip up some rather large ones. A black bear on the other hand can climb a tree just about as fast as they can run and they can run up to 35 mph, so it won't work to run away. The only good thing is that black bear (don't know about grizzlies) don't have very good eyesite, on the other hand they have good ears and a good nose. By the way was the ranger carrying an adequate firearm? So in the end it's a lot like Dirty Harrys' question, "Do you think your lucky punk?"
