Lily Yarnevich of Auburn secures the dance floor Monday while others stand to keep the surface flat at Riverfront-Franco Center in Lewiston. Yarnevich and other volunteers with The Dance Center were preparing the event center for Thursday’s opening of “Off World,” an original, modern dance piece that incorporates conflict, humor, character development, murder and sparkling aliens. Performances are at 7 p.m. Thursday and Friday. Daryn Slover/Sun Journal
