I guess it depends on how much of a bitch boy you are. The average /out/ist will never see a grizzly because they don't leave city parks. Pic related is 3 juvenile grizzlies I saw on a short hike in Glacier National Park.
But whether it's a griz or a nigger, the best advice I can give you is to stand up straight, look threatening, and stand your ground. They smell your white boy fear.
