As usual Sue did a great job rephrasing and answering the question. The only item on the Bug-Out list I've been through in SOCAL are wildfires -- we've had a few here. I stayed for previous fires because they weren't forecast to hit my specific neighborhood. Some neighbors left, but since evacuation was only optional, we stayed. Our neighbor firefighter who was spending time on the line occasionally came home to get some real sleep, so I figured this area was relatively safe. Next fire I'll do the same thing: pack the truck early and watch as it chooses a path. If it looks like it's coming our way I leave. You won't find me dead in the street, garden hose in hand. I'll be 10 or 100 miles up the road at a motel.

Nuclear, radiological? Where at and where's the wind blowing? If it hits a local target I'd expect to know immediately and I'm outta here. . .if the truck starts -- EMP could step on any plans to evacuate. Wouldn't want to be out riding my alternate evacuation tool (mountain bike) when the fall-out starts raining. If I didn't see it or feel it, I stay home and button up -- hopefully the radio is still on line. Fall-out may still be a concern, depends on the wind. Face masks to filter particles would be advised.

My earthquake reaction is identical to Sue's. If I survive the major shake, why leave. Gather yourself and start cleaning up. Wear good boots.
