I was the Project Manager for this event. I worked on it for 6 months and lived in Cleveland for a month preparing for it. We had to design a structure this filled a city square and could stand up to 90 MPH winds, which was building code. The one-piece net was fabricated by the exact company I found in So Cal who built the cargo nets for the Space Shuttle. Kids in schools "sold" balloon sponsorships at 2 for a dollar that went to United Way. The goal was 2 million but we stopped at 1.4 + million.
