Smoke fills the sky outside the evacuation centerHere at the Harris County fire evacuation center in San Diego, the sun isn't quite up yet but you can see the thick black smoke to the northeast above the fires blocking the blue sky and a few twinkling stars.
The fire crews here are watching to make sure the fire doesn't jump the highway to the evacuation center. One way is by controlled burns around the homes in the hills.
The center we're at is about 20 miles north of the border, and a firefighter just told us a number of the 24 injuries here were "international hikers," which we take to mean illegal immigrants trying to cross into the United States. They're coming out of the woods and mountains with smoke inhalation and burns.
