don't forget the after dinner rolls(toliet paper) to figure a years supply 0ne roll per person per week.
we can our own water. i can water when doing the canning to fill up the canner when there isn't enough of the other also in the winter when the air gets dry in the house it adds .
moisture back into the house as will as warm it up.
oh,almost forgot, everytime i empty a bleach bottle, i fill it with water. we have been without power for up to a week before and those bleach bottle of water sure help keep it clean.
I have a book around here some where that tells how much of what to store per person for a year. it takes ages in. don't know where it is right now. but it is here some place.
