"Oh my gosh, it is super fun," the twins' mother, Katie Waechter, 33, of Wellington, Colo., told ABCNews.com. "It's like going to one of those amusement parks and riding those rides. You get the butterflies in your stomach."
On May 4, construction was complete on the Waechter's very own, personalized backyard playground equipped with a large deck that includes a wheelchair ramp down to the yard, a 3,000-pound wheelchair swing the children can roll on to, as well as an elevated sandbox the twins can access with their wheelchairs.
The 15-week-long project was part of Colorado State University's Construction Management program, CM Cares, which focuses on students applying construction skills through community service projects.
