I’m sorry to hear this. They are the horse riders that give all of us a bad name. The riders I go with are considerate and appreciate the bikers who call ahead and go by us slowly. I’m glad to hear that you will continue to be considerate since someday it might be my horse and I that you are passing 😃 Some of us ride green broke horses who are learning how to negotiate trails and the obstacles that come with them and truly appreciate the respect especially when safety is at stake. There is no reason we can’t share the trails as long as everyone is respectful.
