Uh... there are no grizzlies in the Santa Ynez Forest that I am aware of - and grizzly protection was not the intent. Did I say it was? If I were planning to hike in grizzly territory I would pack something to stop it, or at least slow it down - a Mini-30 with a couple 30-round clips would be my weapon of choice.
I prefer using spent uranium rounds- it'll easily pierce a grizzly and, if there just happens to be one walking behind him, it'll take him out, too. Eat lead err...depleted uranium, Grizzly!
