There are a lot of bear stories in the news at the moment - this year there seem to be a lot about.
There was a story today about an encounter with a grizzly that was successfully averted with a can of bear spray:

Although, when you read the article, you'll see that the bear bit into the can. Please note, the manufacturers suggest you spray it at them!!
