Bummer about your trip back from Idaho...
I did most of my Unlimited sheep hunting in the '80s and '90s when I was in my 40s and 50s, AND I had my own horses for many of those hunts.
But, I was 71 when I did my Dagestan Tur hunt in Azerbaijan, and those mountains were steeper and more rugged than any of my sheep hunts here at home, and in Canada.
I did my last Unlimited sheep hunt in 1999 and decided to just apply for one of the draw units and hope for a tag for a monster. Last month I was at my taxidermist's shop and Fred King was there scoring a 180 1/8" ram that a local 81 year old gentleman had shot last year in the Spanish Peaks on a DIY hunt with his son and grandson.
That shows that there's still hope for us geezers.
