I was very surprised & disappointed to read your letter in the ADN. As a bicyclist who regularly rides up DeArmoun Road, I am well aware of the amount of gravel on that road. Apropos to your comments, I was about to call the Muni (but maybe it should have been the State, based on other comments) to ask them to please sweep DeArmoun, a designated bicycle route. Glad to hear this important service is now occurring. You must be whizzing by in your car instead of dealing with the dangerous gravel on skinny tires. Thanks to the street-sweepers - your service is appreciated.
