No, the best advice is to slowly walk away and do not run. Running away is a sign of a prey animal. Humans are not
usually on a bears menu. The most dangerous ones are females with cubs. Running away will trigger the predator
instinct. It was mentioned earlier,but Usain Bolt can't outrun a bear.
I'm no bear expert. My dad managed a campground in Cooper Landing AK. in his retirement years. This was the advice
given to him from park rangers.
