WHEN THE mortgage business melted down in 2008, it knocked a big hole in our retirement. I’d spent 15 years working as a mortgage officer, and there I was at 50, sitting at my desk with nothing to do, my eyelids twitching from the stress. I came across an article online about ranchers getting paid to graze goats as a way to mitigate fire risk, and I thought, I could do that. I’d grown up on a ranch here in Red Bluff [California], and we raised cattle and hogs, so I was returning to my roots.
