This is a great bit of photography - movement, focus, lighting - all work pretty well for me. However, not being of U.S. the pride bit missed me in the traslation. I don't understand the historic/cultural significance. Interpretation is a big bit of some of these challenges. Thanks for the image though - it certainly held my eye.
Overall I like the feel of this image. B/W was a good choice. It's a shame about the powerlines. ;^( Wonder how this might have looked in a full silhouette? The rider is already pretty dark. Just a thought. Good luck in the challenge.
