I'd be tempted to say that what article describes is THE way to stack grass for drying, no matter where you are, because it's based on common sense.
Wooden frames with cross-braces so that air can somewhat circulate within the construction and help it dry, keep the first level somewhat off the ground because that's where most of the moisture is, comb the result to align surface level straws vertically, so that any rain runs off.
I helped make plenty of these accursed things during childhood/early teens summers in Latvian countryside. Mind-numbingly boring for a kid, with added benefit of sunburn and insect bites. The only major difference was that no one would climb on top of them, we'd build them only as high as the pitchforks would reach from the ground.
Now I'm curious, is there any place in world that does (did?) their hay stacking in a radically different fashion?
