RENEE MONTAGNE, HOST:
Good morning. I'm Renee Montagne, with a story of a childhood dream. And when you grew up in the family of the famous Flying Wallendas, that would be walking a two-inch tightrope across Niagara Falls. Nic Wallenda yesterday got special permission to attempt the kind of breathtaking feat that's been banned since the 19th century when daredevils rolled over the falls in barrels. He says his dream is to, quote, "walk down through the mist and walk back out." It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
