An evacuation is different than bugging out. This scenario is completely different than say, an earthquake, because it is relatively localized (contrary to the media reports) A few miles outside the fire area and everything is normal. People aren't worried about surviving the elements with what they have in their BOB's, they're concerned about saving their belongings. If I was in that situation, I'd be grabbing anything irreplacable, pictures, documents, pets, money, antiques, maybe computer stuff. I definitely wouldn't be thinking about food or water or tools, when I could just drive 10 miles go buy whatver I need. I'd probably have some of those basic items already in my car, but for this situation there's nothing really life threatening if you don't have the necessities.
