-f(x) = The Transformation of 20th Century Rural America!

With a stroke of boldness necessary to even type this silly introduction, I can almost guarantee that the topic and substantive significance of this post will be of relatively little interest to many people at all. Regardless, this is something to consider, because one should consider Everything at least once, even if dismissively:

A Question for the Masses:

Do these USDA Census results prove surprising?
If so, does the distribution of highly productive farms in America reflect the shifting lines of the rural/urban divide, tax-related situations for large commercial farms (if this applies?), or the more traditional mode of farm distribution (e.g. grow-where-the-land-is-the-most-fertile.) I know nothing about farming, despite my claims to the vast agricultural dynasty of Ohio, and was spelunking about the census maps by way of statistically augmenting a section of one of my MBTA Essays--however, I was still quite shocked to see that the vast Midwest (even including Kansas, in some of the more East Coast/West Coast TASPer definitions!) is not really the hotbed of vegetable fecundity that I had once imagined!

But then again, what we don't devote to cucumbers and onions,
we give to corn and soybeans and wheat...

Round Two Results: Yeah, We're Still All Farmers Here.
