I noticed that some of the videoss showed mules being used along with horses. Even though I have always had horses, and nevr even thought about having a mule, I would certainly prefer one if a person was trailriding in mountainous areas where the trails were steep.
I used to ride with a friend who owned a mule, and when he took his girlfriend along on a trailride, he would put her on the mule because she was a very novice rider.
Once day, we were crossing the highway on the bacroad that we were riding on. As luck would have it, a semi-truck with flapping canvas covers on his load came roaring over the top of the hill, panicking all of the horses. Thankfully, no one was hurt, although it took a while to get the horses stopped and settled down. During all of this, the mule just flapped his longears a few times, and walked unconcernedly down the road in the direction that our horses had all fled.
Needlesss to say, I was impressed ! When my friend, Gib. asked me if I wanted to ride his mule one day, I thought I would try it because we were going on particularly steep trails that day.
The mule was so surefooted and just confident going up and down the steep trails that by the time we got back home from the ride, I had bought the mule, and traded in my Morgan mare to my friend.
The calm disposition of a mule, combined with his sure-footedness make the mule an ideal trail animal. Yes, they are different than dealing with a horse; but if it is a well-trained mule, most of the differences are positive.
