When wildfires rage close, Perimeter wants to tell you where to go Out the window, a fire is raging — and it’s moving ever closer. Confusion. Fear. A run for the car. Roads open and then suddenly closed by authorities. Traffic jams. A fire break that stalls the flames and then suddenly the flames jump, changing direction. Everyone has a plan for what to do — a plan that gets ripped up the second someone leaves their home to evacuate. In the heat of the moment, everyone needs to know exactly what to do and where to go. Unfortunately, that information is rarely available in the format they need.
