The Southern California Working Snow Dogs, a group of humans and dogs indulging in different fun dog-powered activities for the working dog (URBAN MUSHING!), meet on Saturdays mornings--whenever the weather is cool enough for the dogs--at Fairview Park in Costa Mesa. Pros, amateurs and (mostly) huskies and malamutes meet to pull elaborate sleds, scooters and bikes. Each team contains anywhere from two to five dogs. The oldest dog is 13 years old and is nearing retirement, while the youngest is just three and already a leader. Aw. For more info, just visit UrbanMushing.com. All photos by Keith May.
