I was able to check out a copy at our local library here in Gardnerville, Nevada (just across the Sierras from Lake Tahoe). It was informative. I was quickly able to eliminate Sun City from consideration as a retirement community thanks to the book. The author's main theme was that retirees should stay in their existing communities, where they would be integrated into the community.
I find that is not the case here in Nevada. The communities don't provide much in the way of facilities or support for seniors. And grown children have their own children and lives to live.
So. my wife and I plan to "withdraw from the rest of the country" and move to The Villages in about eight years, when my wife can retire. Looking forward to being a Froggie and living life with other active seniors.
