My church has been encouraging its members for many years to have 72 hour emergency kits and at least a year of food stored. Emergency happens big and small that a kit with basic supplies that you can take with you, use, etc with will give you peace of mind if never used or relief if needed. The year of food in our family is always top in our mind with looking for sales, rotating the food etc.
I am not trying to preach my religion to you but the link below is the resource our church provides as a help in what we call provident living.
http://providentliving.org/. This may give you ideas and something to think about.
The govenment also as a site with resources and advice.
