my favorite type of fishing guiding trip is called a "fish and ride". This is where the guests ride into the back country (no roads,wilderness) on horseback and then are guided in fly fishing for a bit, eat a packed lunch and then ride back to a ranch for dinner. It's fun, but you may be traveling through grizzly bear country. A 44 Magnum is a good defensive weapon to deter them in the rare event of an attack, which is even rarer on horseback. Better to have and not need than to need and not have, I always say. Mules are smart and like to hang around horses and they make good pack animals.
