This thread is of relevance to me because my preparation is centered around two very likely events- wildfire and earthquakes. My thinking is that i evacuate from wildfires and shelter in place, at least initially, with earthquakes.

My earthquake preps do not involve any backpacks but consist of supplies in sturdy containers scattered about the premises (not inside the house). Basically I will camp outside my home and work out a strategy from there.

With fires, I pick up and run. I have done this once and been right on the cusp on two other occasions. That's what backpacks are for. They should be fairly large.

The contents provided with the kit under discussion here are quite typical of BOB contents, although sadly lacking in some areas.

Can't really blame the purveyors of this kind of stuff. They are just trying to makee a living and yes, something is better than nothing.
