Wow! How cool to find this. I've never been a climber, but I have several friends over the years that have. So I'm not entirely unfamiliar.
I met a friend I haven't seen in a couple of years. He had a bad MC crash in India and has basically stopped riding, so he's got drones. He put a smiley face on his 'big dog' because he was using it to film some climbers and thought his drone intimidated some. Great film.
I have a really close friend that is on the down side of his climbing career (He's schooling his grandchildren on technique). I'm going to point him at you, maybe that will convince him once and for all to leave FB and come here full time. That would be a good thing.
Thanks for a wonderful post. I apologize for the novel length comment.
