There is a station not far from my house up by the hyway where they wait for a call. But it is not a fast service, they will also come to your house and transport to the hospital for autopsy and such, they are paid by the body count, but sometimes it is a long wait for them as they have to find the address or site of the pickup,No street names or numbers, and it is hard to get there sometimes, even for an ambulance with siren and lights because there might be a party set up plugging the street and they will have to find another way in and traffic on the roads never pays any attn. to emergency vehicles. Most times we just load em in the back of our own pickups and haul em to the hospital. Coarse at bad wrecks on the hyways it is them that scrapes up the parts. Emergency services in this country are almost non existent.
