I think it would take about one minute to grab my bug out bag (that's what it's for), external hard drive and phone on the way to the door, keys at door.
With the bag I am good for 2 weeks, with access to my car which is street parked away from the property, another 2 weeks.
That is the luxury of time option. I could just walk out the door with nothing, if I could get to my car it is set up fine and a valet key is accessible on the exterior, master key on the interior impossible for anyone else to find.
Me +
= good to go
*My prep is more for earthquake than fire, I guess if it is just the one structure it wouldn't matter. There are hotels to set up in then.
