You know it's Fall in So Cal...

...when you feel the bite in the wind, the nights get cooler, even though the days continue to be blistering hot. Then, before you know it, the leaves have turned, and the Santa Ana winds have come to blow them all away. The air is dry, which is great for your hair (if you're a woman), and really bad for your nose.

If you're lucky, all the winds have blown is the leaves, and the trees are still rooted. If you're lucky, you didn't forget the umbrella outside and your patio furniture is still intact. 

But you really know Fall has arrived in So Cal, when the Santa Anas not only blow the leaves off the trees, but the embers on one, two, or three fires that threaten to burn out of control.
