In the 1970s my father decided to chase a dream of operating a volunteer ambulance service. The small fleet of ambulances was comprised of a few Caddys and one or two Pontiacs. I don't believe there were any such things as the big boxy "meat wagons" of today. Despite his efforts, and my grandmother pouring in about $75K to help, he could not compete with the county and the venture failed after a few years.
