"WHAT'S GREAT THIS WEEK" Courtesy of the Fort Worth StarTelegram A Fort Worth tradition that has symbolized hope and generosity for years now graces the pages of a new children's book. The Homeless Christmas Tree is about a sparse mimosa tree atop a hill on Interstate 30 between Beach Street and Oakland Boulevard that, for years, was lovingly decorated by an anonymous woman as a gift to the homeless in the city. The Star-Telegram reported in 2001 that the woman was Carla Christian, who said she began decorating the tree in 1995 as a reminder that people should make time for those less fortunate. Now, author Leslie M. Gordon has turned the heartwarming story into a children's book. "I've loved the tree for years, and I've always wanted to write about it," she says. The book, $19.95 plus shipping and handling, is available online at http://www.thehomelesschristmastree.com/ and at some participating area bookstores. Quantities are limited. A portion of the profits will be donated to the Big Texas Toy Run and the Chisholm Trail Chapter of the American Red Cross.
