We are headed to the Cody Wyoming area in four weeks with elk tags. While I have experience with black bears (depredation kills, tranquilizing, and a nasty encounter with a sow and 3 cubs in Colorado when I was hauling a pack full of elk) I have never even seen a Grizzly. We will be carrying rifles and bear spray (doubt I would drop my rifle for a can of spray). My question to you folks who have encountered Grizzlys in the woods, at what distance, between you and the bear, would you consider using lethal force for self protection ? I understand your decision may be based on the exhibited attitude of the bear.
