- SuccessfulBring the Biking Back to Crystal$1,310 RaisedGOAL $1,000 Rev. Crystal Zerfoss is a mountain-biking, deep-lake-kayaking, evangelically-UU minister in the Pacific NW. As many of you know, Crystal sustained a traumatic brain injury in January involving the refrigerator door to the back of the head. Her intense healing process (which you can follow on Caring Bridge) has required that she step away from ministry and outdoor activities. But we can bring her biking to her as part of her holistic therapy!
