Troy Brunet, carrying a rainbow flag, and other walkers from the Positive Resource Center, one of the three main beneficiaries, led off the 30th annual AIDS Walk San Francisco in Golden Gate Park Sunday, July 16. The walk has raised millions of dollars over the years for large and small AIDS service organizations around the Bay Area. This year's event drew about 10,000 participants and brought in $2 million, according to AIDS Walk organizers.
