Pyramid Hill Sculpture Park and Museum celebrates Founder’s Day Friday with free admission to its more than 60 pieces of outdoor sculpture and a ribbon-cutting ceremony to dedicate the park’s new entrance art. “Passage,” a large-scale metal sculpture by renowned artist John Henry that spans the width of the park’s entrance, will be dedicated at 5:30 p.m. According to Nanci Lanni, daughter of park founder Harry T. Wilks, it was always her father’s dream to have sculpture for people to drive through when entering Pyramid Hill.
