BACK2THEFRESH (AP) This post woman goes by the name of “D”. She’s always known to smile while delivering mail in Camden New Jersey, even though most residence may not be as friendly. And that’s one of the qualities that separates her from most of her co workers. “D” always delivers her mail on time and she loves to do what she does. In a developing suburb nicknamed “City Invincible’, make sure you remember her name.
