(USA) - The first generation of openly Gay US citizens chalked up a lot of firsts - a Gay-rights march in Washington, openly Gay politicians in office and out-of-the-closet actors on sitcoms. And now, this generation will be the first to have, just in time for its twilight years, Gay senior condo communities. It's an extension of the Gay ghetto, this time with walkers. But at RainbowVision, a development that opened last year on the edge of this high-desert city, a there-goes-the-neighborhood cloud has appeared. Some residents fear that their community could be overrun by an outside element -- straight people. "It does not matter how friendly they are," said Roger Bergstrom, 77, who shares a condo at RainbowVision with his longtime partner, Barry Baltzley, 57.
