I learned to skim stones on a lake in the Canadian Rockies. We went with some friends of my parents and their family, including their children and Gramps, their grandfather.
It took hours but with the endless supply of skimming stones and patience I can only dream of, I got there in the end. And once we were done it was time for marshmallows by the campfire, again Gramps showed us how to whittle a stick to spear a marshmallow and roast it on the fire.
