Moses Alexander governed the land of famous potatoes from 1915 to 1919. As a longtime Western representative of The New York Times, which is well read in these provinces, I feel the rub of faux-rube pandering both ways. Here, people are amazed I can find Twitty, Texas, on a map, and — more surprising, can vouch for the peach cobbler. There, the wonder is that I know which side of the plate to keep the salad fork. Sort of." Why are people upvoting this article? Truly - and I am not being sarcastic here - I don't get it. I read it but still don't understand it.
