Follow photos of Crystal Buchans as she wanders through downtown Atlanta walking along the CSX railroad tracks and under the CNN parking decks. Although she formerly worked as a waitress and a grocery store cashier, Buchans says she is now a drug addict and homeless. Buchans' life turned upside down in 2004 and she has been on the streets ever since. The city announced in early September that it is putting five "donation meters" downtown for people to contribute money for homeless outreach services. This is her story.
