It was a bitter cold Friday in March, and Sal Pinna was heading into the wind on Main Street in Hartford. "Cold enough, but I don't feel a thing," Pinna said. "I guess I’m used to it." Pinna, a Long Island native, has been homeless for 20 years in Connecticut, but he wants very much to get an apartment. He has in his backpack a xeroxed copy of his birth certificate – but that’s not good enough for official paperwork. Without proper identification, Pinna is stuck in shelters, or worse.
