If you don’t know who John “Verm” Sherman is – get reading. This guy is a climbing legend, literally writing the book on bouldering and creating the V scale of route difficulty. He has been out of the game for years now, having sustained a boat load of injuries and moved on to his latest passion – wild bird photography. Now he is back in training to send the most famous bouldering problem of all time – the test piece classic “Midnight Lightning” in the Camp 4 campground at Yosemite.
