If you think of places in Colorado where starts-ups are born, Boulder might come to mind for natural foods, Fort Collins for its beer and Denver as a tech magnet. A prominent venture capitalist wants to spread the love to Colorado's rural areas. Small town starts-ups are our focus today in "The Disrupters," coverage of entrepreneurship in the state.
