Thousands of marchers streamed through the Detroit streets for three miles yesterday to open the U.S. Social Forum. Today, activists from across the country continue rolling into the humid Detroit heat on bikes, in buses, in packed vans and by air to get the conference moving. I'll be posting to Racewire for the rest of week with stories from Detroit and from the Social forum. Today I'll be looking at the impact of the predatory mortgage crisis and what groups here are doing to fight back. In the month of May, Michigan saw a rising rate of foreclosure—46% higher than a year ago—and ranked fifth in the nation for foreclosure filings. Photo: ColorLines/Hatty Lee
