Yes they are Gary. For whatever reason you prepare it is a good thing. Hard economic times or natural disasters will see you dipping into your preps anyways so theres a good enough reason right there. Keep up the good ideas. I personaly have a small stream 9 months out of the year that runs from a spring on my land. As well as a well. I still need to work on my long term water storage. Ive liked some of the gutter rain water catches but I have redwoods that clog up mu gutters so I need to some more work on reseaerching that as a viable 3rd source of water. and storage system.
