Atlantic City, New Jersey (AP) - Penn National Gaming on Thursday became the latest company to scrap plans to build a lavish new casino in Atlantic City. The Wyomissing, Pa., firm announced in a statement accompanying its fourth-quarter earnings that it won't exercise its option to build a new casino on Route 30 in an area far away from the existing 11 casinos. The company's chairman and CEO, Peter M. Carlino, blamed market conditions.
