If you dial 911, the fire department or ambulance comes out to help you.
But who pays for the fire and ambulance visit? In many parts of the country, the fire department is supported by property taxes. But here, fire department services are provided by Rural/Metro, a private company that is paid for by its customers (you) and not supported by taxes.
See Fire and Ambulance Services at SMVE for a description of Rural/Metro services and cost and payment options.
