After going to Grizzly Valley, there is my favorite project as a roller coaster enthusiast. The Grizzly Mountain Speed Mine is the largest and most exciting roller coaster in the entire park, and the miner travels back and forth between the valleys to experience positive dives, reverse falls and high-speed ejection. A total of 3 laps, the first lap is normal, the second lap climbs to the highest point suddenly reverses and accelerates back, the third lap super-accelerated driving, I feel like I am flying at high speed, really cool! It was raining lightly at the time, and our tourists were all wearing raincoats to play. The second lap of raincoat hat flew off. It was so happy and too high!
