Firehouse: Greetings!

2 Things. I am working on some paintings of fire, particularly the western wildfires from this summer.

1.) Got any good pictures or links to pictures you like of fire that are on the internet?

2.) Of beneficial-to-firefighter organizations, which one(s) are the best in terms of least% of donations used for admin costs and secondly, good deeds done as an organization?

Thank you in advance for sharing your knowledge with me.
