I like the amendment, but there's one part that doesn't fit in there, the “unreasonable financial burdens on farmers”. That's just too broad and vague. It's too open-ended. The rest of it's good:
...or impede their rights to grow, save and use seed for planting, including their unrestricted rights to clean, store and prepare seed for that purpose.
That all makes sense, but that's not the way it works here. That part really doesn't fit. If it were out of there, I think I would have no problem with the amendment.
