Something tells me that this is not a practice unique to the United States (and perhaps relates somehow to the cave paintings in France and Spain, the petroglyphs in the American Southwest and in Australia), and probably on trees everywhere. Then again, maybe not. I would like to hear. The urge to leave one's mark.....and to mark romance. The conclusion of the Pennypack Park series continues a bit longer, though no longer about reflections. I leave once again tomorrow, to return early next week. My last craft show of the year.....and snow forecast for Saturday.
