"A lot of people are eager for a definitive signal that the economy is on the mend, but America's small business owners aren't sending that message yet."

When asked whether they agree or disagree that the recession is over for their businesses, 69 percent of small business owners disagreed, only 13 percent agreed and another 18 percent couldn't be sure.
