I have asked about Deaf Smith County Peanut Butter

I have asked at perhaps tiresome length:here, here, here, here, here, and here. Maybe even more times.

And finally Jon Krampner has given us the fascinating and well-recounted story of Deaf Smith County PB (and much much more) here, in Creamy and Crunchy: An Informal History of Peanut Butter, the All-American Food. (Much congratulations, Jon!)
