Dayhike with old friend Jean and new friend Amy, up the Nattkemper-Goodspeed Trail, from Sugarloaf Ridge State Park to Hood Mountain Regional Park. It was a warm and sunny fall day, above the Valley of the Moon in Sonoma County. (A note about Amy: She is an experienced solo sierra trekker. She survived a near-fatal fall in 2003, followed by several days alone, near-fatal infection, subsequent rescue, several surgeries, and ultimate survival and recovery. Check out her book Angels in the Wilderness.)
