We live in rural country and farms are plentiful. Where farms exist, barns exist. And barns often have a beautiful weather vane topping them.
As I have mentioned, I love weather. Our lower field holds a weather station that transmit data to a computer in the house and the National Weather Service. The station is modern, sleek, and accurate, but it is not very photogenic.
A weather vane, on the other hand, can be both functional and artistic. A bright, sunny day may not conducive to a lot of photography, but sun reflecting off copper is quite eye-catching. The puffy clouds in a bright blue sky background adds to the color of copper. Thus, too enticing not to capture.
