Listening on-line

One thing that makes listening to the radio on-line fun is getting to hear the local ads. Occasionally, I listen to KRLA from Los Angeles. One ad I heard last week gave me insight in what it's like to live in that part of the world (I've never even visited the area). The ad is for Housebath and begins, "Now that the fires are over . . .". I can't imagine living in a place that has a fire season. I've heard of a rainy season, a dry season, a growing season I've even heard of The Four Seasons, but I've never before encountered anyone talking about what sounds like a "fire season".
