Older people, like the rest of us, of course have differing tastes and a variety of preferences for how they'd like to live, but it's also the case that as people age, mental and physical capacities can begin to decline. At some point, many people should really just stop driving, or at the very least be in a place where they can get by with minimal mostly short distance driving, where home deliveries of things like groceries are options, where taxi rides are possible, etc. It's hard to see how 2800 homes not near anything else is the ideal retirement community.
Boomers are getting older and we're going to have a lot of old people soon. We should be thinking about how we're going to cope.
