"In light of the rising frequency of human/grizzly bear encounters, the California Department of Fish and Game is advising hikers, backpackers, hunters, and fishermen to take extra precautions and keep alert for bears.
We advise outdoors-men to wear noisy little bells on their clothing so that the bears are not startled unexpectedly by a human's presence. We also advise outdoors-men to carry pepper spray with them in case of an encounter with a bear.
It is also a good idea to watch for fresh signs of bear activity. You should be able to recognize the difference between black bear poop and grizzly bear poop. Black bear poop is smaller and contains lots of berries and squirrel fur. Grizzly bear poop smells like pepper and has little bells in it."
