I worry about bears where I go fishing. A grizzly got one angler near a hole I fished at Castle River. My cousin once had to shoot at a grizzly that charged his camp. Bear attacks are actually quite rare (you are more likely to be hit by lightning).
I doubt there will be any grizzlies in Southern Alberta in 100 years. A shame, but I don't think we can co-exist. Black Bears are not as threatened. There is a grizzly on the California state flag, but there has not been one there in ages.

The last one was killed in Tulare County in 1922
