This thread has me head-scratching for a few moments; I'd never heard of the term "grain elevator" until Galah correlated with the Australian term of "Silo"!! "Ah, that's better!".
Yes, I photographed them many years ago travelling around on my bike, laden with cameras, lenses, notes and enthusiasm, out wide into the country often far from where I lived at the time, watching long grain trains unload at isolated silos — mere shimmering specks in what is often called "Big Sky Country", far from the nearest big town (but often too, central focal points that hint of a town's prosperity). These occasionally ugly contraptions on the countryside are nevertheless entrenched in the mechanisations of country life and what goes in them comes out — as cereal, rice and other staples for the kitchen table.
