Enjoyed the root cellar story, Sharon. It got me to thinking. The further we venture from the basics of nature--and in this era of modern technology we have ventured quite far--the more vulnerable we become. One has to think only of this country's electrical grid or of all the cell towers to get a glimpse of how vulnerable we would be without them. I think there's an article lurking in there somewhere. I'll have to give it some more thought.
