Apparently, I've been spotted in the wild, photographed, and posted on the net:
(Thanks for the link, Steve).
The photographer is from Marin as well, though I don't think from my immediate area, or she'd probably have recognized me. (I WAS recognized by a local grocery clerk! Hi, Max!)
I have photos I took (from the Segway), and the full story, awaiting the time to organize and write.
