"Salmon-ing" on a Sidewalk?
On my "short-cut" commute into work, I'm encountering a cyclist who is salmon-ing (biking against traffic), but on a sidewalk. I will refrain from commenting on what else this cyclist is or is not doing as this will surely divert the topic.
As this cyclist also happens to be commuting to the same office park where I work, would I be "within bounds" to make a comment, or should I keep to myself?
