Looking up from Kranjska Gora, a buzzing winter resort in Slovenia, where I joined Lauren and the children for a few days, I saw Prisojnik and Razor, both of which I climbed last summer. That was my second time up there. The two peaks looked magnificent in the bright winter light, but the last time I climbed them I could barely see more than a few steps ahead of me. A bit more than six months later, I could clearly remember looking down at Kranjska Gora from each peak. The memory of the fog has evaporated.
