A few weeks ago we had our driveway repaved. Our house is eighteen years old and it was well past time. The company did a meticulous job, but last week while doing yard work I spotted a piece of our old driveway under a holly tree near the garage. The chunk was triangular, about one foot across on the longest side and four inches thick. It was lightly colored compared to the new tar-black driveway shining in the afternoon sun.
