There is no NOBO climb up Dragon's Tooth as you're already walking the ridgeline of Cove Mountain. The SOBO climb is like a StairStepper on level 10 that just keeps going and going; the amount of rock-work involved is amazing. I went up on a warm afternoon and really felt it, even though I had already been on the trail a week and was in great shape. Here's a picture of the last scramble to the top where they decided to forego additional rock steps.
