From what I've seen on TV, seems like a lot of people have been driving just far enough to be out of the immediate evacuation areas and then just hanging out in their cars rather than driving to a shelter or to homes of friends or family. I have no idea what proportion of evacuees are doing this, but you see plenty of them on the local news very close to the fire line. I suppose this is only possible because life still goes on fairly normally just outside the evacuation zones. You can eat in a restaurant, use the bathroom, buy groceries, etc. Very different from evacuating from a hurricane where everyone is going somewhere.
I was just watching some TV during my lunch break. I'm a bit surprised that all of the TV programming has reverted to normal programming already. CNN was the only channel I flipped through just now that was showing fire related news. The skies above me are filled with smoke and we're supposed to watch soaps and Divorce Court?
