this past winter, i was on some rental skis (so demo bindings), i knew the dins were at 9, but I was planning on having a mellow groomer day so I thought "fuck it, I don't need to tighten them". Well, on one run I was in some moguls, saw the end of the mogul field and started to strightline out of them to freedom... BUT the first mogul I hit, I hit the uphill side of it, my skis popped off and flew up and hit me in the face. Cut my nose right open and cut my upper lip. 3 layers of stitches, 13 inside my nose and 12 outside my nose/upper lip.
