The trustees of a 122-year-old amusement park in northwestern Pennsylvania have hired an attorney to file chapter 11 bankruptcy in hopes of preventing a sheriff's sale of the park to satisfy more than $910,000 in overdue county, school and municipal property taxes, the Associated Press reported yesterday. Officials for Crawford County, Pa., and the local taxing bodies have threatened Conneaut Lake Park with a sheriff's sale, though they've yet to formally pursue that option. Mark Turner, the executive director of the Economic Progress Alliance of Crawford County, says that the group still hopes to redevelop, revitalize and expand the park. The bankruptcy filing is needed to freeze the park's assets and prevent the sheriff's sale while the park maps out a plan to repay creditors all or part of the $2.5 million owed to creditors in addition to the delinquent taxes.
