Do you know the difference between and buffalo and a bison? I didn't either, but what we commonly call a buffalo in North America is really a bison while the 2 main buffalo species live in Africa and Asia. The American Bison has a large shoulder hump and has a much more massive head than it's foreign cousins.
Now that you are armed with that invaluable information, you are prepared to seek this cache. (Just kidding, you could have found it without knowing the difference!)
