Seems they only have about a dozen horses that they use in the series over and over. These same horses are ridden all over the known world and by friends and enemies alike. It’s gotten so obvious that I am constantly saying to myself things like “Oh, now Ragnar’s mortal enemy, Earl or King so and so, is riding Ragnar’s horse [that he just rode in the scene before in Kattagat] in Wessex, England!”
By the way, that’s the gray with the tail that has been badly and scraggly pulled at the top. Too funny.
And notice how that black Clyde mix is so danged lazy that his riders have to kick like fiends to get him to move?
