My recent trips across the prairies look a little different than when I made road trips as a teenager. For one thing, the iconic wooden grain elevators are few and far between in favour of larger cement terminals. The concrete terminals are farther apart and not as charming as the originals, but they hold a lot more grain and are more efficient for rail loading. Some small towns have worked hard to preserve their local grain elevator, so you can still find them in some places (the one in Chaimberlain seems to be in use, judging from the grain auger. The dry prairie air and beetle-killing winters seem to be pretty good at preserving the old elevators, so probably at least some of them will be around for a while.
