The town of Rockwall, Texas, has a few claims to fame: Bonafide Betties Pie Company, where "thick pies save lives"; the mega-sized Lakepointe Church; and Lake Ray Hubbard, which is lovely until the wet, Texas heat makes a shoreline stroll feel like a plod through hot butter.

Now add to that list: Rockwall is home to the middle-school winners of NPR's fourth-annual Student Podcast Challenge.
