There's no denying the city of Detroit is facing immense challenges. Abandoned buildings and homes dot the city's immense landscape, poverty and unemployment is pervasive, streetlights are commonly dark, debt is high and safety a common concern. But there's something else in the air and it's palpable. It's called hope. Not your airy-fairy kind, one found in empty rhetoric, broken dreams and listless conclusions. This hope is backed by entrepreneurial savvy, pragmatic solutions and ballsy conviction.
