Horseback riding

Travelling on animals
''Some animals are strong enough to carry heavy loads on their backs, so why not us? If we can select the most adapted and docile breeds to do so, and how to teach them to obey our orders, we could travel directly on their backs instead of using carts and heavy chariots attached on their backs. It would make travelling on it more practical and fast, and it would open new perspectives for warfare as well!''

Potential Requirements
