Anatomy of the grain elevator

I came across a light-hearted, yet detailed description of the insides of a prairie grain elevator and how it works. The link will appear when you click on the title of this blog. I totally agree with the statement that the new "inland prairie terminals" just aren't photogenic. The author also wonders what symbol will replace the elevator once there'll all gone. He suggests the bald eagle, which is already taken by our neighbour to the south. I would suggest the gopher be given serious consideration. ("Richardson Ground Squirrel".) Here's the scoop on this cute little rascal: http://people.uleth.ca/~michener/main.htm
