Notes:
I don't like how ugly most of the track gaps look in this game (sorry),
so I took special care to make the jump segment look as if a section of the track had fallen away.
I based the shape of the track on the airflow of a tornado.
I really like how easy it is to make a good-looking track, that also plays as well as it looks.
If you haven't noticed, I've taken to the "Stunt" aspect much more than the "Rally" aspect of "Stunt Rally"

Track is hard to play in reverse, because the jump segment requires a lot of speed to land properly in reverse, and the straightaway is very steep, almost too steep to climb.
Fixed in 1.1
I suck at driving this track, because I'm not good at dealing with low traction (yet?).
