This picture seems to have appeared only a single place on the web: Pixdaus, uploaded by Robot (who, as of the last time I checked, had submitted 5,847 other photos).  I would love to know who took this.  The Pixdaus links below may stop working soon (Pixdaus appears to modify them regularly, perhaps attempting to deter hotlinking).  The picture is entitled “High Ride”, tagged mahout.
