"Sentinel: something that seems to be standing guard or keeping watch." Grain elevators are often referred to as prairie sentinels, and judging from the definition of the word, sentinel, it certainly applies. This photo I took of Plato, SK shows a large grain elevator standing in the middle of the village. Imagine that the elevator is the village guard, big enough to look over everything and to keep any misdeed in check. If only elevators could talk and tell stories of life in their villages. I guess we'll have to leave that up to the town "gossips", or storytellers.
