Pacific Beach Surf Shop, celebrating 47 years of business, is holding a Grand Reopening Party Nov. 21 to showcase its new Action Sports Environmental Coalition Greenroom. The store has undergone a remodel that includes an organic and sustainable section and a stage to host live music and speakers. In addition, the shop will host film screenings, art displays and more live events. Randy Strunk, PB Surf Shop’s owner since 1994, has been an environmental activist for years and wanted to make the shop more active, or interactive. “I wanted to do more of an event-based shop,” he said. Strunk hopes this is the beginning of a wide range of surf and beach community events as the shop moves toward becoming a “community surf shop.” The grand reopening will include live musical performances by the bands Humanlab and The Growlers. The event is scheduled from 6 to 11 p.m. Nov. 21 and the shop is located at 4150 Mission Blvd.
