Bannockburn, Illinois

Median home value: $1,000,000+
Mean retirement income: $129,256

Bannockburn has a country feel, with at least 6 miles of equestrian and pedestrian trails. It is also a mere 26 miles north of Chicago. Most lots are 2 acres to 4 acres, many with barns and horses. According to the town's marketing materials, it is focused on becoming a pioneer in eco-friendliness. It encourages residents to install rain gardens -- gardens with a design and plant selection that takes advantage of rainfall and stormwater -- and has a K-8 school that installed a "closed-loop geothermal system" to heat and cool the building naturally. About 13 percent of residents are over 65.
