One thing I keep is entertainment for my kids. When we loose power they go insane. I keep cards, books games, etc.
Keeping morale up is key in a bad situation. Especially for the little ones.
I have a Condor plate carrier that I am putting together. I have soft Armor now and I am saving for plates next. So far I have a Med kit, mag pouches and working on some Kydex bits as well.
