Would love to have horses haul me in and dump me off sometimes, have and will continue to use horses at times, good ones. However, I've spent 19 days in the Spanish Peaks this summer and for what I've been doing, they'd have kept me from seeing more than half of what I have. Horses cannot walk where a stong backpacker can. Never. Them are the facts.
Idea is to ride in to a camp and then walk from there or ride into your hunting area and walk from there. I hunted MT Shavano for goat some time back. Too rugged to ride, but we walked two mules in with packs to base camp and then climbed about 1500 ft.
I don't think anyone is saying you ride everywhere.
