Local environmental awareness nonprofit Experience Green will move its annual Earth Day celebrations from Hilton Head Island to Bluffton this month. Instead of taking place at Shelter Cove Community Park on Hilton Head as it did the last two years, the third annual celebration will be at Carson Cottages on Calhoun Street in Old Town. The festivities -- which include cooking demonstrations, live music and an obstacle course -- will run from 11 a.m. to 4 p.m. April 27. Admission is free. Abby Wirth, program manager for Experience Green, said the organization moved the celebration to Bluffton to try to expand its reach.
