Alonzo Carter tinkered with the transmission of his getaway vehicle, a minivan that he also sleeps in. It’s drivable, but it only goes in reverse. Carter, who lives in an encampment of mobile homes in a privately owned lot on Wood Street in West Oakland, was getting ready for an expected eviction attempt by the property owner. I went there on Sunday afternoon to see what it’s like in the tension-filled hours before police show up to clear people out.
