Now that is what you call a proper backyard coaster!
That name though. "U-Shaped Rollercoaster"
Classic China.
You can't ride either if you happen to have "action inconvenience" are an "alcoholic" or have "carsickness" or "seasickness".
That's most of TST not riding then after Fireworks.
Though it doesn't say if you have "nudism", so that's a bonus at least.
