Thank you for your words! From what I heard talking to way more experienced climbera, one can train to take altotude sockness better, so you shouldnt be so sire that you cant do it. Just need to work towards it, climbing Mount Kazbek might sound harder than it ia from me, because I dont have a lot of experiwnce as well.
Also, I wish I could come to Rockies one day as well. Mountains from other contineta looks more mysterious:)
