A pirate ship is a type of amusement ride, consisting of an open, seated gondola (usually in the style of a pirate ship) which swings back and forth, subjecting the rider to various levels of angular momentum.
My people and kids are waiting for a adventure ride. But the most of parents in China had no such wonderful experience in their childhood. They maybe more like tree climbing for fun. The cache is inside a tree but a little higher so that you need climbing skill or supervised your kid to climb the tree for it. Climbing is easy with "handrails"!
Did you climb trees as a kid? Do you let your kids?
