I've never had it, I don't think so anyway. Not many of our mountains go over 3000m(10,000ft) and above 2000m(6600ft) it's generally nothing but rock. I guess altitude plus a few degrees north means our alpine starts lower. There's goats up above 2000m but not much else, unless it's a pass that is also a travel/migration corridor but they don't have a lot of reasons to stick around that high up. Very little feed, no cover, water is also hard to come by. Most of my hunting is done 2100m and below, there is one exception in our area, a plateau at about 2300m that has feed, cover, and water. Don't get me wrong I may not be going as high as some, especially you guys hunting mule deer at 10,000ft(unheard of here) it's still plenty rugged and often very remote. No cell service, miles from any real road, if something bad happens it's going to be a problem. Hope I never get it, sounds terrible especially if you're solo, which I often am.
