“Leonard ‘Pumpkin’ Ambrose lives just down the street from the house where he grew up. Derrick Soo lives 2 miles from his former family home, Delbra Taylor is a mile from hers and Gwyn Teninty can walk the distance in 15 minutes. All four grew up here, in Oakland. And they succeeded in their own ways, each at one point owning a home, which was once considered the very foundation of financial stability. But now, as they grow older, they are among the surging number of unsheltered people who spill out around freeways, along train tracks and through vacant lots.”
