"Unsustainable" was the byword Wednesday as more than 250 people gathered in Roanoke to hear three politicians piped in from Washington and two think-tank types discuss the nation's debt of $15.6 trillion. Ferrum College hosted the visit to the Hotel Roanoke & Conference Center by the National Debt Tour, a traveling symposium on the perils posed by deficit spending, entitlements and a coming demographic crisis… "Do you want a government that takes care of you from the cradle to the grave, or do you want a government that is limited in nature and allows the most opportunity and prosperity and freedom for the individual?" said freshman U.S. Rep.

The Committee for a Responsible Federal Budget puts on the Debt Tour, with earlier stops at Harvard University and New York City.
