I was riding down the road and saw the "Loose gravel" sign. Rode through fresh gravel over an inch deep in spots for about a mile. Yesterday I came to a "Flagman Ahead" sign and there they were, riding back and forth on a roller compressing the stuff. Had to turn around and take an entirely different ride, where I saw more signs on some of the side roads I often take. These are back roads and it takes months for all the gravel to clear to the shoulder. And the roads will be rougher for years.
