Things you don't want to have a lot of in your driveway:
Cary and I were out walking around this evening, looking at signs of spring and enjoying the last light of an absolutely beautiful day, when he noticed one of these sharp & pointy metal triangles in our driveway. They look like they were snipped from a downspout or some flashing. We started looking around and collected a good-sized handfull of them. Yikes. They must have just recently come to the surface, maybe because of the recent heavy rains, because neither of us has punctured a tire. We'll have to keep an eye out for any more sharp surprises that might show up.
