Rural Carrier Christopher Ahern was delivering mail on a January day in Wiscasset, ME, when he spotted an older man sitting in a snowbank, waving at him.
With temperatures hovering around 12 degrees, Ahern immediately stopped to check on the man, who was disoriented and inadequately dressed for the frigid weather.
The Postal Service employee called 911 and stayed on the scene until emergency responders arrived.
The man was taken to a hospital for observation.
