According to World Memorial officials, the flag tour "represents the resolve of Americans and their quest to live free."
The flag also honors living public safety personnel-firefighters, police, EMTs and SAR workers-willing to risk their lives for others.
The flag was donated to the non-profit World Memorial organization by a group of U.S. businessmen through the American Legion Post J.B. Clark Post 149.
The flag's cross-country tour began in San Diego on Aug. 10, 2010.
After the tour wraps up in California, the flag will head east, again, to Pennsylvania, New York City, and the Pentagon, as well as Arlington National Cemetery, on Sept. 11.
By Sept. 11, the flag will have toured in all the 50 states of the union. Tour organizers said they are still looking for a final home for the big flag.
