Locks hang on a fence along the Cliff Walk in Newport, Rhode Island July 14, 2015. They say the whole world loves a lover, but in Newport, Rhode Island, at least, not everyone is fond of the so-called “love locks” that sweethearts are leaving along the resort city's famed seaside Cliff Walk. Hundreds of the padlocks left behind by tourists as romantic tokens now cover sections of a chain-link fence along the route. Each is meant to represent the bond lovers shared during their visit. By custom, the key is thrown away. (Photo by Brian Snyder/Reuters)
