I have just recently begun getting ready for any disaster situation by stocking up on water ( one gallon bottles from Wal Mart). I have also but together basic medical kits in vehicles and house. My next purchase will be a water filter. After that I plan on stocking up on food. My goal would be cheap long lasting food that can hold up against the elements well ( I may put smaller portions in each vehicle). So far my mind is set on Ramen noodles and caned tuna. Any ideas, suggestions?
