Trish Karter, 52, jumped on her bike in late April and began a 15-day journey from Atlanta to Boston in order to raise awareness for the plight of the homeless. The chief executive officer of a baking company, Karter spends each evening at a shelter where she decorates gingerbread houses with the families and shares their stories on her blog: dancingdeer.com/ride. She spent an evening last week at Southeast’s Naylor Road shelter.

How do you get the word out about homelessness if you’re riding 100 miles each day?
