A ten year old!! That's incredible. I have been slightly obsessed with rock climbing since I myself watched Free Solo a few months ago, finding every documentary comparable, plus reviewing countless interviews. I have not seen America's Best Idea, so thanks for the recommendation!
If you haven't seen the Dawn Wall, definitely check it out, also Meru :)
Yes, those are good also. I am not a climber, and definitely not comfortable that far off the ground, but I do live somewhat vicariously by watching some of those movies.
