We have practiced leaving in less than 30 minutes. The older children have had drills packing the kitchen without us. I load up the foods stores, while wife loads the pre-packed travel clothing and hygiene supplies.

If we decide to shelter-in-place, my personal is filling all my ice chests from the freezers---saving as much of our frozen meat supply as possible. If/when electricity is lost, I'll spend the first few hours smoking the hams and jerking the beef and venison. I have gas and wood-fired grills, with plenty of fuel. I have non-electric back-ups for processing the meat. I probably couldn't save all of it; but I bet I could jerk 90 lb or so of meat, and smoke 30-50 lb of meat so it would last a week or so. Once that is accomplished, I'd host a neighborhood cookout with all the stuff that will spoil.
