Lean close to a Jeffrey pine on a warm Sierra Brooks afternoon and the bark smells faintly of vanilla, a small surprise of this forested neighborhood on the eastern side of the Sierra. It's Tree Time Services works among those tall trees, handling tree work and lawn care for homes tucked into the woods. Winter loads the limbs with heavy, wet snow, and spring is the season for clearing what came down and taking a hard look at what still hangs overhead. A yard with branches trimmed back from the roof and grass mowed beneath them feels open and calm under the big mountain sky. The difference shows the first time the wind moves through the canopy.
