Hi Carolyn,

Bonn was a great city for bike riding when I lived there.  And while it can hardly be called a city, Davis, Calif., was a terrific bike city when your great grandparents lived there.  Also Palo Alto, Calif., was so bike friendly that Jack and I typically only used the car when we bought the week's groceries or were going up to the City (SF) for a concert.  For that matter Walla Walla is bike friendly.  My "commute" to campus and later the UB was on my bike.  As for Louisville . . . after a few scary encounters early in our life here, my bike hasn't left the garage.
