It has nothing to do with what kind of cloth rural America is cut from. It has everything to do with how many doctors (particularly e.r. doctors) hospital beds, ICU beds and ventilators they have per capita as well as the distance from the average resident to one of those ICU beds, not to mention that resources on a macro level to do things like turn massive convention centers into impromptu emergency wards and anyone care to venture a guess on percentage of elderly.
Milli, however, does have a good point though on spacing, which will work in Rural America's favor.
