Took the Lightweight Backing Class offered by the Loma Prieta Section of the Sierra Club. Two days in the classroom, followed by an overnight backpack trip in Henry Coe State Park. Learned a lot! My packweight at the trailhead was 19 lbs, including food and water. This is 9 lbs less than last week at Hetch Hetchy!The track is messed up; we started at Bear Mountain, which is at the upper right corner, and ended up at the HQ, which is at the left.
