I grew up riding a big wheel in a very poor section of the south side of Syracuse New York. There was one kid in my neighborhood whose parents were well off had a green machine which was an expensive big wheel. I always wish I had one. Later in life I raced go-karts at the Waterford Speedbowl in Connecticut. I painted it green and my number was 19. I selected 19 to help me remember my wedding anniversary. GreenMachine19. Kind of rhymes also.
