It is like any regular Sunday afternoon in the Castro, with locals and tourists alike strolling through the historic center of gay, lesbian and transgender history. Suddenly, heads begin to turn and ears perk up to listen curiously to a strong pulsating baseline emanating from somewhere.

Simultaneously, an alluring smile forms behind reflective aviator glasses atop the muscular 5-foot-9 body of 2010 the March Bare Chest cover model. John Lopez dances along the median of 18th street between moving and waiting cars, moving his hips to the beat while waving a sign that reads "Tighty Whitey Car Wash."

In a dressed-down look of t-shirt and jeans, San Francisco Board of Supervisors District 8 representative Bevan Dufty looks to Lopez as he moves among the cars and responds with a playful smile on his face .

"In this environment, you have to make things fun," says Dufty.

In the environment of Castro while the Bare Chest men wash the cars of individuals willing to donate, many people look on with curiosity, amusement and laughs. They watch the guys having fun as they wash cars in a makeshift parking lot which stands behind the local Walgreens.

The Bare Chest Calendar website states that the South of Market Bare Chest Calendar (BCC) started in 1984 as a way to donate funds to San Francisco's AIDS emergency fund. In 1999, San Francisco's Positive Resource Center was added as another beneficiary. These two groups benefit from those donating their image, time and work to help those with HIV and AIDS.

B.J. Patnode, the 2010 Chairman of the Bare Chest Calendar Committee, adds that the Bare Chest calendar raised over one-hundred thousand dollars from sales of its 2009 calendar.

The Tighty Whitey Car Wash was created by 2010 Bare Chest model Coop Anderson, who participated in a similar fund raising event in Canada before settling in San Francisco three years ago himself. Anderson says the Tighty Whitey wash shows people that raising money can be fun. He adds that at the same time it allows people to be active in the community that they are apart of while helping those affected by HIV and AIDS.
