I got one of those email invites, to work on my specialty (accessibility features). It was a bit of a fiasco as my chair got stuck in some mud on the trail. MZ kept walking and talking while my wheels spun and dug me ever deeper into the slime. Thank God some other guys came along. I think it was a Honda service manager courting a new mechanic, because they both had tools and the older guy had a "Honda" patch on his shirt. Anyway, I lived, but I didn't get the FB job.
