Yellowstone National Park

Chicago, IL, July 22, 2019 -- A massive volcanic eruption at Yellowstone National Park yesterday wreaked havoc for the organizers and balloon captains of the 9th Annual Hot Air Balloon Regatta, causing disappointment among surviving spectators and participants. The eruption, which had not been anticipated by the regatta's organizers, severely disrupted the day's events and may force Western Ballooning to cancel the project altogether for this year.
