About 500 people from this area are expected to join an estimated 8,000 marchers in Washington DC, demanding an end to AIDS.

Val Sowell, an organizer with ACT UP of Philadelphia says, “We are all bringing props that represent different ways we can end AIDS. So, some people will be bringing in pill bottles, some people will be bringing condoms, some people will be bringing in bills or fake bills. All of these represent what it really is going to take to end AIDS.”
