Join us for a walking tour of four Railroad Square stops featuring appetizers, drinks and an interactive component at each location (a costume fashion show, a set design extravaganza, a choreography demonstration and a photo exhibit).  The evening concludes with live music and a dance performance at 621 Gallery.   Dancers from the area's only all-youth pre-professional ballet company will perform selections to the backdrop of vibrant artwork by Joe Roache, Ry McCullough and John Chang.
