Fire at the end of our street

This evening I was changing out one of the heads on the sprinklers in the front yard when I noticed some smoke down the end of our road. I didn't take much notice as I though it was someone's barbeque but before too long it was thick black smoke and obviously more than that. About ten minutes later the sirens started and CalFire turned up. It was a piece of ground with long grass and trees that is a hang out place for teenagers, and it was well and truly alight. Someone said that some boys had been seen running away from the area after the smoke started and they believed they were smoking and that started the fire. It is so dry out there, that it would not take much. Luckily CalFire put it out quickly. Ironically there was a hill fire off Hwy 101 tonight too.
