Think I'm gonna have to agree with Philip here. RCM's pics remind me of a time when I lived in Lake Tahoe. One day I walked out onto my back deck and wasn't really paying attention to my surroundings. I didn't even notice (at first) the black bear that had wandered right up to the railing.
Well, long story short, when I did notice him, he was no more than 10 feet away, and fortunately, on the other side of the railing. Without even thinking about it, I yelled at it (hopefully I didn't sound like my little sister!

) Anyway, the noise startled him and caused him to run away.
(Hehehe, I say "run" away, but I assure you, he left at his own pace!)
I believe he was going after my garbage cans. Fortunately I beat him to them, because I heard they will tend to return to good places of food. I never saw him again after that day.
