What would the properties be? I was thinking some of the biggest fires or most noteworthy fires. Such as MGM Grand Las Vegas, Chicago Fire and San Fransico Fire/Earthquake. Any other suggestions? Or would they be fire stations? Which ones?
I was thinking fire departments, with an image of their patch on the property space. But then I'm stuck with deciding which F.D's to use. Do I use all big city F.D's or volunteer departments? I kind of like your idea about famous (infamous) fires.
