One evening, years and years ago, while probably doing something I shouldn't have at a place I shouldn't have been at and all the while I probably knew better, I somehow wound up puttering my derelict 'B around the pedestrian sidewalks of the University of Albany (NY) campus.
I swear I don't know how I got from car roads to pedestrian sidewalks, but I certainly remember the collective groan from the spectators that gathered to watch me try and ease that thing off a curb to get back onto a road. I'm amazed I didn't get arrested.
