Picture the following hypothetical situation:
A patient with a medical problem presents himself to the parking valet at a suburban hospital. The valet stand is located immediately outside the Outpatient Department door, within 150 yards of the Emergency entrance. It’s less than a two-minute walk to the ER, whether through the building or the parking lot.
Fade to two paramedics in the cab of Medic 9, three miles away, staring with incredulity at the radio. Have they really just been dispatched to the parking lot of Local Suburban Hospital for a medical aid right outside the doors?
Yup, and so has Engine 684.
