Many years ago, I took a trip to Louisiana. The cemeteries look like poignant little cities, because they have to bury everyone above ground, due to Louisiana being below sea level. Something I saw there chilled me to the bone. I saw many family plots where everyone in the entire family died days apart, including the children, some just months old themselves, because of the great Yellow Fever epidemic. That kind of thing would still be prevalent in this country, if not for those vaccines that animal testing gave us.
