I used to have to put like that dark blue chowder all over the seed before it was put in the hoppers and, folks, that job sucked. my dad would go up and down and mostly I just sat in the truck waiting until he radio'd that I needed to get ready and then I'd have to rip open all the seed sacks and dump a scoop of that stuff into them and mix them up and then dump them into the hoppers when he got to me. feel like I've probably got cancer from whatever that stuff was/is.
