LOUISVILLE, Ky. (WHAS11) -- What first started as a small gathering of local musicians playing in Tyler Park, has grown into a massive event drawing people from all over the world.
More than 30 thousand people are expected to converge at Waterfront Park this year, and it's all thanks to Louisville native JK McKnight who started Forecastle in 2002.
The event has grown from a community event to one of the country’s most anticipated summer festivals.
