The reward comes in getting to an accident quickly enough to extricate the victims and get them to a hospital in a timely manner so they survive. Neither one has ever delivered a baby, but they came close a time or two. Crawley got one expectant mother to the emergency room barely in time. His teen-age daughter occasionally babysits the boy who was born that night, and Crawley enjoys telling the lad how he took him for his very first ride. It's almost a privilege to be called in to help during those last months of their lives.

It's never easy to lose a patient. Council EMTs take turns being on call for 12-hour shifts. Two are on duty at any given time, in town and available during that time. The work means uncertain hours and interference with family and personal life. Many people serve for a few years, then burn out and quit.
