Episode Transcript

NPR. Huntsville, Alabama is growing fast. About 18 people move there every day. And you can see lots of reasons why. It's where the rocket that put the first man on the moon was developed. There are plenty of space and defense sector jobs, a big music venue. And in the center of town, there's an art museum and a pond where Rachel Ramos and her daughter, Reina, are feeding the ducks.
