I think Kaelin is on to it. I have been following trends in Gay retirement communities. Typically they are new so they attract a younger 55-62 clientele. There are some specifically designed that way. I have seen interviews with some of the residents who expressed the pleasure in being around similar people, and not having to worry about being ostracized by straights in a typical development. I love the idea of being in a safe environment, at least while at home. Some place to recharge until the business battle tomorrow. My thoughts would be 5-6 houses, communal pool, backyards open to each other with gardens, benches, places to talk, etc. Fencing at front sides of houses to reinforce idea of separateness. A lot of estates are set up with central courtyard type configurations. The ideas are limited only by the mind and it's ability to break out of ingrained stereotypes.
