Scavenging on bulk trash days is almost second nature to us. We know that our neighborhood's old couches and bags of leaves are picked up every third week. These items hold no interest. It's the other little things--gnarled ropes of Christmas lights that someone was too frustrated to untangle, a not-quite-past-its-prime doormat--that we relish digging out of other people's junk piles. It's this give-and-take culture that's allowed Freecycle, a project that started in Tucson, to spread to more than 1,500 cities, according to www.freecycle.org. The D-FW group is one of the largest, boasting 5,490 members in its online community. It's a little like a classified ads forum, except that everything posted must be free. And nothing's too crazy--people offer everything from old lightbulbs to pianos and request anything from Girl Scout uniforms to bikes. You may not find exactly what you're looking for, but it's a lot easier and less degrading than trying to drag a discarded dresser four blocks under the pitying eyes of a city of Dallas sanitation crew.
