The Americana sounds of Yarn will ring out proud and true on September 1 when Frenchtown in Hunterdon County will host the 20^th Annual Riverfest, a free celebration of life along the mighty Delaware River “with an ecologically and sustainability-focused lens,” according to the town’s website. Between Yarn, 67 local vendors, 20 local musicians, Viking Paper Boat Races, Doug Miller The Magician, strolling musician Nick The Bag-Piper and the Native-American drumming, prayer and dance of the Lenape tribe, there certainly will be plenty to do in the two locations of Sunbeam Lenape Park and Downtown Frenchtown.
