Lynn Hummer has long been an animal activist, environmentalist and volunteer. After protesting nuclear power plants in the 1970s, she enjoyed a career in music for much of the 80s—an enormous portion of her work raising money for animal rights. After marrying and having children, her commitments transitioned into volunteering for her children's public schools. In 2006, upon discovering that over 100,000 American horses were being sent to slaughter in Canada and Mexico, she decided to get involved. She founded the Pregnant Mare Rescue in May of 2006, relocated her family to Santa Cruz County, applied for non-profit status, and began pulling pregnant mares out of harm's way. While working full-time and raising a family she remained relentless, saving the horses from abuse, abandonment, and trips to the slaughterhouse. Eventually, the horse rescue inspired new programs, especially those for children. The Pennies for PMR and The Wonder of Horses are two of the highly-enjoyed, well-received programs designed to help children experience "horse" and the value of giving. She and her husband of 30 years enjoy ranch life, the coastal fog, and the wonderful feeling of making a difference.
