    "Note: This example use case presents an approach to using ArcGIS to find out which areas are within a four-minute drive time of a fire station in a particular city. While the data is real, the scenario, analysis, and resulting decisions are hypothetical. The purpose of the example is to illustrate the type of problem that can be addressed using the drive-time areas."

    "Prompted by a series of articles about emergency response times in a nearby large metropolitan area, a reporter for the local newspaper is writing an article on fire response times in her small city. To accompany the article, the reporter wants to include maps showing the areas of the city within a four-minute drive of a fire station. Her research has found that's a common standard for many cities."
