To sell or not to sell? The question was posed by people who sought free investment advice yesterday at the Byrd Theatre in Carytown. Joe Scott said he came to get input from an unbiased person. “No one is trying to promote their company or sell anything,“ he said. “This is a wonderful opportunity.“ Scott was one of about 25 people who had one-on-one consultations yesterday as part of a Your Money Bus Tour, a financial-education event sponsored by the National Association of Personal Financial Advisors, TD Ameritrade Institutional and Kiplinger’s Personal Finance magazine.
