Yin and Yang are twins (no, not The Yin Yang Twins). Some people may think that they would be complete opposites, but this is not true. Each has a different way of looking at things that are mutually beneficial to them and those around them. They grew up in China and picked up geocaching while attending university in Texas.
They each decided to place a cache. After hiding the cache each brother put a series of coordinates on a map. Even though each brother did not know where the other put the cache they new exactly where it was when they put the maps together. This combined map is shown below. At first glance one may think that this place is in GBP. However, upon close inspection you can see it is in China. The landmarks are a dead giveaway.
This is Yang's Puzzle Cache.
Unlike Yin, Yang prefers a more traditional container and hide.
