On a birthday outing with my sweet husband, obilon, after a great breakfast at one of our favorite restaurants he brought me out here to visit Shell Mound, a place we had never been despite living in the area for over 40 years. As we went along I was finding a few that I had not gotten in the past. When we approached this location he mentioned that there used to be a cache here. Apparently it has disappeared. Well, it being a guardrail, obilon was eager to repopulate it! However, I grabbed a couple of containers and strategically placed them first! HA!
