All he had left of his father's belongings were the yellow crampons. He didn't know exactly when he had worn them. The only people who would were long dead. He only knew he had worn them to walk over ice. At the cave of the snow monster? He didn't know. Maybe. They'd been sitting in a cardboard shoe box. Presumably his father had put them there. So he had the shoe box as well. He hadn't thought of that.
That was the thing about saving things. Who would he give the crampons to anyway and what meaning would they have for that person? His sons? Maybe, but he'd have to take his time in order to explain and didn't know if he would even get that chance. So he'd have to think of another way.
