San Francisco Bay Area bike rider Brian Warkentine enjoys the trails in Don Edwards San Francisco Bay National Wildlife Refuge.

Brian posted this photo for Panda Portrait Wednesday over at Google Plus. I love the sense of movement here.

Panda Portraits have their origin at Flickr, where a user with the nickname of “faster panda kill kill” began posting awesome self-portrait-on-moving-bike photos, and it just spread from there.
