Upstate New York’s Saratoga Performing Arts Center (SPAC) has had a productive year, and if reports from within are to be believed, the organization is well on its way to healing the divisive splits that left it on the edge of insolvency a year ago. But time doesn’t stand still for rebuilding purposes, and SPAC is facing a daunting array of challenges in the year ahead, from expanding its audience base to expanding its board. A major marketing push is on tap, and audience services such as online ticketing are a priority as well. Still, SPAC needs millions of dollars to stabilize its depleted endowment, and is still trying to worm money out of the New York State Assembly for physical improvements.
