Welcome to our Solar / Planetary Walk which has been established in memorial to Alfred Piff, a longtime member of MBG and supporter of education for all. As you travel along the walk, you will experience the scale model of our solar neighborhood. Our walk is approximately .79 miles, and each planet is marked by Planetary Art Posts created by Nancy Thomas. Scanning the QR at each post will give access to information about each planet. Enjoy your walk!
