BEDFORD STUYVESANT - A Bedford Stuyvesant volunteer ambulance corps may cut services to thousands due to money problems, according to the corps' co-founder.The one ambulance, 20 person volunteer corps is operating out of a city-owned vacant lot. Corps co-founder James Robinson says he fears the city will kick them out at any time, even though the borough president promised the group a new trailer to house operations. Volunteers are forced to sell fried fish and food to stay afloat. Robinson says since he helped start the corps in 1988 ambulance response times in the area have gone down.The Borough president's office says getting the corps the promised trailer could take as long as a year because of processing delays.
