Of all the stories about people re-creating themselves in this dismal economy, Star Grigsby's could be the cheeriest.
Grigsby, a 48-year-old nursing assistant and mother of five, managed to stay above water working two jobs until 2005. That year she suffered a work injury that required cutting back her hours. Her marriage was disintegrating and one of her kids was having serious problems at school. Then she discovered her home's mice infestation -- about 300 of them.
