Last weekend I took my three year old grandson to the science museum. The same place I had taken my son – his daddy – when he was three. The day was clear with a crisp chill in the air. Landon was wrapped in the same coat my son had worn. We walked the same nature trail and threw stones into the same pond. He climbed on the same playground equipment. We sat at the same picnic table, snacking on apples and cheese, just what his daddy liked at that age. Although nearly thirty years separated the two visits, it was as though no time at all had passed.
