And every single time for five years we have had all of the volunteers we’ve needed to perform our tasks and do the job the way we thought it ought to be done,” he said.Last year flags were placed on the graves of veterans in 28 states, he said. This Sunday, volunteers will help create a large visual display downtown.“We’ve asked for several hundred volunteers to come down to the great lawn at the waterfront to help us spell out USA with 25,000 great flags,” said Moore.Louisville’s main branch library has also opened an exhibit displaying photographs taken from people in New York City on September 11.
