This is a really wonderful post. You offer a clear, logical explanation and avoid jargon when describing technical material. I don't like the looks of the bag inserted on the side of the animal, but then I'm a fervent animal rights advocate. I had just been reading about sagebrush and how some animals find it palatable at different seasons, so this article fit right into that. I will upvote later because my voting strength is a bit depleted. But I am following you.
