My god, when will people learn to stop interrogating their pagers? It says there is an incident of X type (RESCUE, STRUCTURE FIRE, RURAL FIRE, HAZMAT, GENERAL ASSISTANCE) at a LOCATION.
How is that not enough information? You have a general idea of the incident, it allows you to select which truck you take, then you drive to the LOCATION see what the incident ACTUALLY is then deal with it. SIMPLE.
Smoke in area/smoke sighting at given location, still means that you drive to an area and look for the smoke, then extinguish the cause...
