Rain poured through the roof of the old Black Canyon, Arizona, fire station, making the floor slippery and rusting the tin that covered the roof. Nonetheless, the one ambulance and fire truck that would fit into the aging metal shed still faired better than the other five vehicles parked outside. Those vehicles were not only pelted by rain and hail, but Arizona’s scorching sun baked them during much of the year—rotting the tires, fading the paint, and drying out the parts and equipment. Parking the vehicles outside also meant that the theft risk was greater, which increased insurance rates.
