we think that this playground has some resemblance to the bridge to terabithia. The trees represents the 2 trees where a rope is tied to 1 and both Jesse and Leslie swinged together.Perhaps,we can locate the trees at another location and construct 2 loops each at 1 tree. The thick ropes will then be tied to each loop and a knot will be tied at the bottom of the rope,so that children can step on it and swing around. The rope will not be too high, so that the children can swing on it. Parents should guide they're children .
