I just went rock climbing here, near Monterrey, Mexico. I was really high above the ground. It was a "multi-pitch" climb, which means you go to the end of your rope, then set up another anchor system while clipped into the side of the cliff. I was climbing with my brother-in-law-in-law, Jesse McGahey, who is the climbing ranger at Yosemite. And Maia, a friend from Yosemite.
