At one time, SDC had at least two of those "big wheel" bicycles. I remember D.A. Calloway and John Corbin Goldsberry were both pretty good at riding those things across the town square. Guests enjoyed watching "citizens" ride them, too. I was invited, but declined, to ride those bikes by John. I didn't want to fall on my butt on the town square in front of everyone. There is a trick to getting on and off them, and to keeping them under control. My guess is the bikes are long gone, but I cannot say for sure. Thanks for helping stir some fond memories.
