Crib Goch in the rain, luxury !
I recall a "memorable" trip when we did it covered in 3 inches of melting slush. I'd taken a workmate who wanted to do something a bit more adventurous than the Cotswold rambles he'd been doing with a local group. I mentioned it was a bit "airy" but he said he'd give it a go. We lent him an ice axe and explained its use - totally useless on the slush, but hey ho, and off we went. I'd rather forgotten how exposed it was and we should have bailed out when we found it was slush not good snow, but on we went. Anyhow, after a worrying traverse with me by then realising I'd totally misjudged the decision to take a novice, or do it at all in those conditions, eventually got to the end of the exposed bit and let my mate know it was OK from then on. He'd done rather well to be fair, but he looked me in the eye and said "That's the worst thing I've done in my entire life and I never ever want to so anything like that ever again"
