Am I the only one who spent a lot of time effort and money making a backyard setup that ultimately did not work? Mine was originally designed for my friends sloped yard so it only has a 5 ft drop in, but his parents weren't buying it. It then got transferred to my flat backyard and it simply does not provide enough momentum.
So now it sits, only to be used in the winter. Has anyone else built a setup that didn't pan out?
