VIDEO: Since Friday, a Scottsdale Fire Department crew has been helping the California fire crews battling deadly fires. The crew of four firefighters is working 14-16 hour shifts and are primarily focusing on the Nuns Fire, which is ripping through Napa. "The most challenging thing is the wind. Just the way the wind changes in the California region, it blows in all different directions," said Jay Robinson. Robinson is one of the firefighters. He says his main priority on Sunday was to help homeowners go back to their homes.
