THE SECRET HOMELESS CAVES UNDER DOWNTOWN Officers on HPD’s Homeless Outreach Team show teevee reporter Robert Arnold a secret den favored by a portion of Downtown’s homeless population — tucked under the Louisiana St. bridge over Buffalo Bayou. Dubbed “the caves,” the not-tall-enough-to-stand-in space snakes along the bridge, further back than Arnold’s flashlight can shine. Layers of occupied and unoccupied sleeping bags, clothing, and trash cover the surface, and Arnold describes the scent as “thick and unrelenting.” Arnold’s report doesn’t specify how many people are living in the warren-like hideaway, but from the pictures he shows, it’s easy to imagine dozens. “We’ve had whole families in here,” explains police sergeant Stephen Wick.
