When Pennsylvania’s Mountain Laurel Performing Arts Center closed its doors only five months after opening, arts supporters and state officials were aghast at what appeared to be a classic case of mismanagement and overreach. Now, the state Auditor General’s office is getting involved at the request of Pennsylvania legislators, investigating the decisions and deals that led to the construction of the $35 million venue. Mountain Laurel, located in the Pocono Mountains in the northeastern part of the state, was to have been the summer home of the Pittsburgh Symphony Orchestra, and planned to host summer concerts by the Philadelphia Orchestra as well.
