There was something else I wanted to write...
Funny experience with a blader this morning. I came up behind him. There was a stop sign up ahead, and we were approaching a couple of people out walking, so I was content to drop out of warp and coast until we cleared everything.
We passed the peds, safely navigated the intersection, and then the blader stuck out his left arm and gave a thumbs-up, moving all the way to the right side of the pavement. He hadn't turned around to look at me. I wasn't making any noise. I had no idea how he knew I was there.
As I went by him I saw he had a mirror on the helmet he was wearing. Very cool! I said hello and waved after I passed...
