We ran from one, after we saw it had bad fur when it stepped into the open. Kinda got outta site and left the area before he got too close.
I missed one with an arrow from about 15yds, which startled him. He never knew where I was. Was windy and the wind was in my favor.
A third brown bear on Kodiak Island came up to within about 7yds before seeing us. At 7yds saw us, and stood on rear legs to get a good look at us. Dropped to all fours and woofed at us. Then slowy turned and trotted away. We decided it was on the small side of shooting before it got that close. But he continued coming in. We had two rifles shouldered just in case...
I decided I didn't like calling in brown bears all that much after the one came in so close to us.
