Oh I'm fully aware of what your hinting at. Used to be much more of an issue.
Until you bring out of area resources in to fight the fires and locals don't get work....changes things fast. But many different situations come into play when you deal with ignitions by people. Mental health, economic pressures (to get work or hide crimes), cultural, hero worship (people want to be the hero so start fires to be the center of attention putting them out), or just plain bad luck and stupidity.
Always something new to learn and new experience to be gained is all I know.
