I don’t climb. I’m not a climber. I would describe myself as a lot of things: a young professional, a skier, a Beyoncé fan, a beer drinker, a bookworm, a bike lover. “Climber” is just not on the list. I don’t care that I’m not a climber, but it’s this time of year that I find myself at barbecues, shaking my head in general bewilderment as people passionately “talk rock”.
