Thankfully I and many of my neighbors have been able to stock up on all sorts of supplies purchased from private industry sources such as Walmart, Sam's Club, Kroger's etc...
I think we'd have a much harder time trying to grow or build these supplies by ourselves or buy it all from the limited stuff available from farmer's market (and I'm unaware of any hand-made solar cells, gardening tools, or coolers available nearby).
I guess the only other alternative would be for the government to supply me and my neighbors with all that stuff...but isn't this thread against that?
Sometimes I get confused...
