I could almost do a standing daily feature on the interesting story du jour about Los Angeles in the New York Times. (And maybe I will.) Today it's a garden story by Claudia Steinberg about a couple who live in a 1959 Zenith camping trailer they plopped on the roof of a converted warehouse at Fourth Street and Alameda. Bridget Vagedes and Timothy Krehbiel own the building and use it for their jewelry business; they just like living up on the roof downtown near SCI-Arc. "Nobody even knows you're there, but you can observe everything that is happening down in the streets or just look all the way to the horizon," says Vagedes. Before you ask: neither name shows up in the LAT archives.
