A recession start up story. Being laid-off is an opportunity for self-employment, but entrepreneurship is even tougher in hard times that lead to layoffs. A Marketwatch video profiles a company that was born after its founder was fired in the 2002 downturn. "I think if you knew all the challenges, you probably wouldn't do it," said Fred Ackerman, president of Black Sheep Adventures, a travel company.
