This is the first place that I moved to after retiring and selling my large home. It's a age 55 Del Webb development with two golf courses and several hundred individual homes. I lived there for six months of each year and the other six months in New Zealand. I had many good friends there and enjoyed the community very much. I miss Sun City but my present abode is better suited to my current needs. https://suncityroseville.org/
We lived in Sun City West Arizona for a number of years. It too was a Del Webb community. I still send and get emails from friends there even though we are now back living in Florida. It had population of approximately 29000. There are Del Webb communities all over the country. Tried golf once, but never had any interest in it. SCW had a great RV club that we took man trips with.
