Another of my dad's saying... this one in regards to when we used to feed pigs... he said " kick a pig every time you get close to one... as it is either going to trouble or coming back from it."
Another thing my dad told me years ago, when I came up with the idea of building a farrow to finish pig barn. He considered my plan for a few minutes and then he said" Have you considered picking bottles out of the ditches? I think you would make as much money and you won't stink when you come in the house". I think of this often, and it was very sound advice.
