The Night Glow is an exciting event where balloons are lit up with extra decorations and lights to dazzle the night sky.
And on Sunday, one more sunrise launch and more of the Harvest Festival. According to information provided by event organizers. The Saturday Night Glow is one of the most popular features, according to event organizers:
"Festivities begin at 6:00 PM and include a live performance by the talented youth musicians of the Bram Brata Steel Drum Band and a Kids Zone, sponsored by Milne Fruit Products. Night Glow begins shortly after sunset, weather permitting, creating a spectacular display of light, color, and fire."
