Our Rotary booth volunteers included Bonnie and Bob (first shift), Darby and Krista (not pictured) (second shift), and Alice and Duane Clark for the final shift. 
The vintage bicycle was remarkable - the two smaller wheels steer in response to the hand grip in her right hand.  It was designed just for women.  The device has a name made up of several words, including "rotary".
