This picture from the wiki link above brings back memories. For some reason the few commuters working that day didn’t want to drive through the smoke.

“Drivers scramble up the embankment to escape from Interstate 15, as the Cedar Fire crosses the freeway.”

It’s a shot taken looking to the north on I-15 where it runs through MCAS Miramar. As evident in the picture, the fire jumped I-15. Fortunately, there wasn’t much fuel and room to run on the airfield side (left in the picture), so the fire was stopped right there. This was one of the rare occasions I found myself wearing an N-95 mask to drive. That was miles north from where the picture was taken, the air wasn’t quite as thick. This is one reason I bought a real respirator.
