This one's been floating around my HD for a while. It was originally pure Canyon, and then was Island-in-Canyon for a while, until I decided I really liked the grip that the Lagoon car has on that concrete.
The track has a lot of boosters, most of them red, and your average speed is probably up near 500 or so. There's only one part (hard left at the bottom of the loop) where the car will typically slide just a tiny bit, but in general, drifting is your enemy here (including the offroad section--you can do it without having to slide a centimeter).
The track is complete with intro, replay, and GPS cams, and I'd love to see some replays on this. Any feedback is welcome!
Big thanks to xrayjay and TGYoshi for the custom bits--the track is much better than it would have been without them!
