Fantasy/ Renessaince genre. What is a good system for sending messengers? Owls have been done. Ravens have been done. Humans are good, but fraught with woes. I was thinking of a relay system with greyhounds. Hounds go from one town to the next and back. So hound 1 goes from Capital to town A and back. Another hound goes from town A to town B and back. Et cetera. The hounds then rest at their destination and only return when a message is sent back. I would send people too depending on the importance of the message. A letter to your great Aunt Matilda would be sent by a human carrier.
