Yeah, they're more or less reasonable about the bug out bag thing, but I don't think they're encouraging it due to reasonable concern for the well-being fo the 'flock.' They're doing a local needs part about what to do in a disaster about once a year (in spite of the fact that there's never been a large-scale disaster in the area) just to keep a certain level of fear in the R/F. They want the R/F constantly paranoid about when the GT might start so as to keep them in control.
It's never said in the disaster preparedness parts where people should go in an emergency, but in the "do as you're told even if it doesn't make sense" type talks, they tend to put across the idea that the GB is going to have an inside scoop as to when the GT is starting, and they're going to call us all to the KH for refuge.
