OK, so I created this thread so we can post about our backyard park. As of now we have 2 x 90' runs with a 20' flat-down box on one and a 16' adjustable rail on the other. The sliding surface is carpet, which is either wet down with water or covered with snow. With the backdrop of Blue Mountain Ski Area, it is a nice place to get away from the crowds and short seasons. We are working on a at least one new feature for the spring and possibly a foam pit.
