If you don’t have a camera with you you can’t take photos. This is why I usually have mine with me.
I was driving home with Cerys when we saw smoke not too far from the house. I went in to paparazzi mode and got these photos. Fortunately it was only a big pile of junk on fire, but it did take a lot of engines to put it out.
As an added bonus, around the back of the building there was some hidden graffiti that looked more interesting with all of the smoke.
