STAIRWAYS REVEALED: There are several secrets piled on top of secrets when it comes to the stairs of Los Angeles. One is that our many historic and winding and atmospheric stairways are not as known as they should be, even among people who've called LA home for a good long while. And if you are aware of them, and we should add that many locals are, you might not know where to go and find one, unless you live on top of it. Santa Monica Press recently released a book by Charles Fleming detailing the secret stairs. "URBAN HIKERS" WANTED: If you're tired of your walks around the block, and you're up for it, look into our city's spectacular stairways for health and history. The paperback debuted in April and costs $16.95.
