As I sketched this scene, a parade of people in these motorized wheel chairs passed me in all directions, sometimes as many as 3 at a time. Each one was unique in how it had been customized toward the needs of the owner. They're pretty fast, so I had to sketch fast to get an impression. One man came by a couple of times and I was able to add a bit each time.
At our two meetups, I was able to do quick sketches of two of our members. Sorry, Kalina and Deb, I meant to offense by the poor likenesses.
