The Harris Center stages have hosted more than 1,500 performances in the five years since “A Chorus Line” opened the Folsom venue, and now you can explore the facility – even backstage – as part of the anniversary celebration. Tours of the center – it started out as Three Stages at Folsom Lake College – are accompanied by “tech talks,” an open dance rehearsal, and an arts organization fair and more. 9 a.m.-3 p.m. Saturday, March 12. Free. 10 College Parkway, Folsom.
