I call BS on that SO. I have a brother that lives in Sun City. When I last visited him a few years ago, the people in that community were having block parties and turning off their TVs and taking strolls almost every evening. My brother, his wife and me and my wife included.
15 years of my mother living there and I call BS back.....if you are before 8pm there may be activity rarely, but after 8pm it is a ghost town. Specifically so you know.....I spend most of my time in Sun City West. Sun City 10 years ago was even worse, but younger people are still moving in, and Sun City Grand does have 60 year olds, but for the most part after 8pm it is a ghost town. Talk to a cab driver who services these communities and let them tell you about lonely and isolated old people who moved their for their dream only to have a spouse die and be left isolated with a over priced home. Talk to my mother who had to drive folks to church, dental appointments, and doctor appointments in her job how isolated and totally depressed people are once they commit to the good times in their early 60s.....the golf course, the pool etc.......I call BS.
