It is a bit frustrating to have bikes use the sidewalks all the time when there are so many people about. I suppose they feel it’s quicker (and perhaps safer) than navigating the streets. But even the ones on the streets in Madison tend not to obey the traffic signals.
As a side note, my pace while walk is much like the one who’s hunched over and sweating, moving from right to left. Moving isn’t really my thing.
