As I was topping out on a tough 5.8+ crack climb in Keene Valley (Adirondacks), I peeled off and headed towards the ground 75 feet below.
5 pieces of pro were placed in the crack.
Zipper - big time.
4 pieces blew out.
The 5th and last piece (that no. 4 hex) held.
My partner held a strong belay.
I bounced sideways, 2 feet from the ground. I was white as a ghost.
That no. 4 hex saved my life and is never far from me these days as my good luck charm.
