That's pretty cool Dennis.
I've long wanted a couple mules. Mule owners are biased, but every one tells me they are smarter than a horse. Having seen horses do some really stupid things, I find that easy to believe. I've never liked horses.
An old guy I talked to one time that used to hunt with mules in the Rockies said if you want a horse to go down something dangerous he knows will get him and you hurt, he'll do it to please you. A mule will look at you and say "You first, dumbass."
I live 4 miles from my dad, so I'm hoping to get one and him get one also, and alternate keeping them in his pasture and mine. Maybe in a few years.
A couple of guys that I work with, have mules, and use them in Co. for elk hunting.
There opinion is the same as yours. A mule will get you there, but a horse.....maybe not.
That being said a flatland horse is a totally different animal than a horse born, and raised in the mountains.
The wranglers up there will take the colts onto the mountain trails to get them used to what is required.
