Seattle dog's rush hour ride: on the bus, by herself, weekly
SEATTLE -- Public transit in Seattle has gone to the dogs. Commuters in Belltown report seeing a Black Labrador riding the bus alone in recent weeks. The 2-year old has been spotted roaming the aisles, hopping onto seats next to strangers, and even doing her part to clean the bus -- by licking her surroundings. "All the bus drivers know her.
She sits here just like a person does," said commuter Tiona Rainwater, as she rode the bus through downtown Monday. "She makes everybody happy. How could you not love this thing?" When the dog got off the bus - without an owner - at a dog park last week, it piqued the curiosity of local radio host Miles Montgomery of KISW-FM.
