Groundwork Cincinnati is excited to offer this unique experience along the Mill Creek Greenway Trail the evenings of 9/23 and 9/24 for Green Umbrella's Great Outdoor Weekend. SPACE WALK, on the Mill Creek Greenway Trail, is an after-dark, immersive visual art installation designed to convey the true scale of our solar system, both in terms of the size of the planets and their distances from the sun. Following a linear path spanning 3/4 of a mile and at a scale of 3.5 Billion:1, this walkable installation replicates the vastness of space in a tangible way. The Trail also features green infrastructure, edible forest gardens, restoration sites, and other art installations. This event is from 7:45pm - 9pm each night at 4520 Spring Grove Avenue, Salway Park Northern Parking lot. Please use the link below to RSVP.
