Thanks Deb.

I have an excellent point in case .....
I just got back from my lunch break. I went out to the park again to see what I could find. When I got back, I heard a very noisy bird in the tree near where I park. I spotted him .... a small little brown bird ... not very "interesting" as birds go .... but it was close, and chirping ... so it would have made a cool shot with beak open. My camera was all packed up. But ... I remembered this point and got my camera out.
Too late ... the bird was gone.

So ... that is one negative example. I can give you dozens and dozens of positive examples.

Like the blue jay out my office window yesterday at lunch time. If I had not had my camera here at the office with me, I would have missed some great blue jay shots. I will post the best one at my site soon.
