It doesn't really make a difference what type of animal you want to pack, a person needs to spend some time and effort learning how to pack.If not your 2-3 hour pack will tune into 6-8 hours because you are stopping to repack on the side of a mountain every 1/2 mile.
The reason I use mules is that if you get to the point you can't carry a pack,which I never could, sooner or later you will get to the point you can't walk any appreciable distance.
Learning to ride and take care of livestock when you are younger strechhs that " Can't Walk" scenario out another 5-10 years. That is where I am at now .
