A collection of people gathered in a hearing room at a Washington, D.C., government building last week and expressed a curious demand: equal access to the sun. "I would say that this is a matter of moral responsibility to the people and neighborhoods of this city," testified the Rev. Peter Spann, of Promised Land Baptist Church in Washington. "It's a matter of justice." Behind him, supporters held up long-stemmed sunflowers in a show of solidarity. Their issue was not the sun's light, but its energy.
