Nervouse at all?
Just nervous it'd run away before I got my camera out! No really, I was above it and in the Sierras the bears are harmless. They are much more scared of you than you are of them (at least that's how it should be).
We have had bears where I live, and people ask me if I worry about hiking in the area all the time. I really haven't been worried at all, but haven't met one face to face yet.
My husband actually chased one off our porch that was getting our hummingbird feeders this August. I wasn't home yet and missed it though.... rats! :0(
Blessings & Safe hiking!
