49.9 I bought it at a special price. It took two hours to drift. If you remember to play, you will go there early. We will start queuing at 11:30. We will queue up at the downstream to take the car to the gate. We will start drifting at 12 o'clock. All of them will drift to play at 14:30. If we go too late, we will queue up to wait for the boat. We are relatively smooth and the price is very high. Suitable for children to play, not exciting
