SONOMA, Calif. — Maia and Mia Bravo stepped outside their house on a bright summer day and sensed danger.
A hint of smoke from burning wood wafted through their dirt-and-grass yard anchored by native trees. Maia, 17, searched for the source as Mia, 14, reached for the garden hose, then turned on the spigot and doused the perimeter of the property with water.
