A couple of things I would like to add, if I may. As long as my parents, and eventually me and my siblings, hold on to our vast typewriter collection, they will never completely disappear. From everyday use, of course, but there will always be hidden private collections.
And as far as no-till farming, it is also done largely in an effort to prevent topsoil erosion and stream pollution.
Please understand that I am not picking your article apart. It is great content and I enjoyed it. I just wanted to add to it. Thank you.
