Track Tennis turn 17 I took a few of my own liberties with the rules, considering no one else wanted to add on, and the track really needs to be finished. While I finished the track, the coaster still needs supports and what not, both of which (considering i'm a beginner) i'm very bad with. Basically, if I decided to support it, it would be like 20 of the same prefab and then 20 of a different prefab.
