I clicked on the link, and looked at the aerial maps of my hometown Indio, CA - 1953 (then a town of 5,000 - the city limits then were 6 square miles in area), 1972 (when my Mom moved in from San Bernardino - it had 14,000 then) and 1996 (after a quarter of century of rapid development and population growth - 40 to 50,000). Today, Indio is 35 square miles (28 developed) and home to 90 to 100,000.
