Here’s a video from Rumbling Bald, North Carolina, featuring several three-star problems:Slave Driver (V3; it’s a really great line and a great place to start in this section of the boulderfield); Clear Water (V9/10; difficult opening moves set up a big throw to a sloper from good but small crimps and a fidgety heel hook); Optimus Prime (V8; the several tough moves up this short face really pack a punch. Hit this one in prime (cold) conditions); The Sail (V4; pretty easy opening moves lure you into a high crux throw).
