Either way it's a good investment.
I believe that something will happen ... It wouldn't take much to tip the scales, I thought about this during the "horrible blizzard" we had this year. I went to Kroger I believe the third day...shelves were basically empty, no meat, water, milk, bread, eggs...etc. .
My wife was so happy to not be panicking while everyone else was making last minute trips to the store, and when the shelves were almost bare like unclear.six said. That is why I do it- the level of safety and security that my family felt, glad that I had planned ahead for the "what ifs". It's my job.
