A butterfly gut. A gust of wind. A tree branch for balance. A safety grab. A bird’s-eye view. A sticky situation. A goggle-strap adjustment. A new board. An old board. A moment of truth. A sketchy sideslip. A nervous cough. A rock to gap. An endorphin blast. A distant valley floor. A butt check. A sound vacuum. A plummeting stomach. A yelp to the backup troops. A momentary self-doubt. A new respect for gravity. A hidden shark’s tooth. A 30-second rag doll. A zero-error margin. A both-foot stomp. A powder wheelie. A sweet spot. A vicious fear. A blind rollover. An element of surprise. A commitment.
