Ha, Ha!!  Photo shop can do wonders!!!   

Thanks for the kind comment.  I believe you are asking about the waterways in one corn field.  HERE, usually the road goes out the top of a ridge, and the first field down does not require much for grassed waterways, but by the time you move down the slope 2 or 3 strips, the terrain gets more defined, and water gets more concentrated, and very good waterways are needed.  They blend into the hay fields pretty well, but stick out in corn fields from above.
