4th Fest Preparation 011

Volunteers Anita Ditz, front, and Gary Mayhew are illuminated by the red explosion of a 10-inch shell during Tuesday's test launch. Ditz, in charge of announcing the size, name and shell type, ticked off each successful shell's launch, while Mayhew, the chair of the pyrotechnics committee, captured video of every shell's flight in order to verify timing for the choreography to be used for Sunday's show.
