This up-tempo dance track by electronic duo The Chainsmokers features vocals from singer-songwriter Halsey. With references to being broke but passionate, this anthem to youth became the first number one single in the United States for both Halsey and the DJ pair.

Continuing our tour up the East Coast of America, we reach the state of Delaware, where we meet pioneering wine producer Peggy Raley. For her, each vine is like a child, needing special care and attention to flourish and grow.

Peggy started her winery together with her father, and she keeps his office just as it was when he was alive. Further north on an Atlantic City beach, John Gowdy has carved out a niche for himself as a sand sculptor.

In a moment of reflection, Delta Goodrem airs her self-doubt and asks whether she’s been living her life right. Taken from her album Wings of the Wild, the Australian singer-songwriter describes the song as a letter to life.

John explains which tools he uses to create his marvellous sand sculptures, and why the finished works of art need protecting from the people who come to see them! Further north, at Toms River, we meet Lindsay Harrington, who works for a museum’s insect zoo, and is on the beach with colleagues trying to net a big catch of invertebrates.
