Ellen B. Parkhurst, wife of another New York minister, celebrated the advantages of bicycle riding in Washington's Evening Times. "Of course I do not believe that bicycling is immoral," she said. "A girl who rides a wheel is lifted out of herself and her surroundings. She is made to breathe purer air, see fresher and more beautiful scenes, and get an amount of exercise she would not otherwise get. All this is highly beneficial." —Wheels of Change,
