I've been always ready as a Suburban prepper.
My city hall has always recommended a minimum 3 day supply in the event of a Natural disaster but I always thought that was far too little. We saw hurricane Sandy and Katrina , these took weeks if not months and in some region none at all.
thank you kerrislravenhill, 3 day supply is definitely not enough, maybe 3 weeks or a month would be more realistic. Yes every disaster wouldn't last just 3 days. To be safe i would top up what i already have
