I have an extra refrigerator in my garage that I stock with pop. (Yes. I grew up in the midwest and don’t call carbonated drinks soda) I allow my grandchildren to help themselves without asking permission. Over the holidays, one of my grandsons stuck a Coke in his shoe by the front door. I can’t think of a better foolproof method to remember a can of pop for the road. How smart is that? The kid will go far.
