That was GWN, which I assume is Great White North.
I usually move around in my bike, and whether I use the road or the sidewalk depends on several factors, like the quality of the road, wideness of the sidewalk, traffic, amount of people on the sidewalk etc… I use mostly roads, I can go faster and on a smoother surface, and if I use the sidewalk I go at reasonable speeds and very careful of pedestrians. I agree that passing pedestrians at fast speeds is not only dangerous but very rude, those people are assholes.
