Norfolk — Once a refuge for weary travelers, Norfolk’s defunct downtown Greyhound Station now hosts dozens of the city’s homeless. A phalanx of tents — most elevated onto pallets — sprung up last Saturday inside the chain-link fence surrounding the lot where buses bound for D.C. or Charlotte or beyond once idled. The location is temporary, a stopgap until the city can find a more permanent shelter location, said Sarah Paige Fuller, who runs the city’s Community Services Board.
