OT What do you call those things that water farm yards.
I want to read more about them.
They can be 800 feet wide or more, in sections 80, maybe 100 feet wide, and they hve engines for each set of wheels, which use big truck tires, which are synchronized so they advance the same amount, in order to keep the line straight.
Who of you have never seen one of these?
They use them on the Eastern Shore of maryland, and a lot of other places, I think
