White deer are almost mythical beings. Almost every culture has a legend about them.
One Native American legend states that when two white deer come together, all the indigenous people will unite. In Japan, another story goes, 800 years ago an entire herd of white deer appeared to celebrate the opening of a temple. European stories either talk about the misfortune suffered by hunters who killed one or the fruitless attempts to take one by people like King Arthur.
After having the chance to spend time with a deer that was mostly white, I understand how they have achieved that status.
