OK peregrinos, this first-time pilgrim (leaving SJPdP on May 19) hopes to learn from your experience. What was the SINGLE smartest "unexpected" item you included in your backpack? Keep it to one item, please, and (may I suggest?) skip the basics. I hoping for examples of items I would NEVER have considered taking! Maybe even little "luxury" items that weigh essentially nothing but that greatly enhanced your Camino experience. Be creative, now!
