I have run into the same exact issues. Almost to a T actually.
My friend a couple years ago showed up to my house out of shape with a beer in one hand and a cigarette in the other.
He lasted exactly 2 days at 11,000' before I had to take him to the hospital in steamboat springs after a panicked walk through the blowdowns for 2 miles back to the 4 wheeler...(long story but his health was getting very serious very fast)
I returned to the mountain.
People dont understand what high country hunting is until they experience it.
To answer your question. Yes I hunt alone most of the time. But I dont like to hunt alone in the west. Wife's orders. Its the one thing I dont argue about.
