There's a point where you come to the spot you know will be your camp for the night. Sunset balances like a coin on edge on the horizon, one more day well spent. You're tired, you're caked with trail dust and stale perspiration. Whatever's on your back has been your only company for the past six days. Sixteen years in the business taught me that you can't give a piece of gear a satisfactory test if you're somewhere comfortable and convenient.
