More than 500 participants in the AIDS/LifeCycle, a 7-day bike ride from San Francisco to Los Angeles, commemorate the 30-year war against AIDS in San Francisco. More than 2,500 riders from 11 countries will begin their 545-mile trek on Sunday, June 5, the same day 30 years ago that the Centers for Disease Control and Prevention reported their first case of AIDS. The riders will raise more than $12 million for the L.A. Gay and Lesbian Center and San Francisco AIDS Foundation. Photo/AIDS-LifeCycle, Susan Goldman.
