JACKSONVILLE, Fla. -

One Spark organizers say they are "humbled" and "blown away" by the growth of this years One Spark festival.

Sunday they announced that more than 85,000 people joined One Spark in Downtown Jacksonville on Saturday, bringing the estimated total for the first four days of the festival to more than 235,000 people. Last year an estimated 130,000 attended the five-day event.

They invited everyone to come out again for the closing ceremonies where around 3.5 million dollars of crowdfunding money will be awarded.
