I know these fellas are prone to be good doers', but does anyone else's sport a cresty neck?

We have only owned one purebred ourselves, but he had a cresty neck - and that kind of went with the territory of being a stallion too..........

BUT having seen a number of purebreds in the flesh - yes, a cresty neck tends to go with the purebreds - both the mares and the boys be they gelding or stallion
