Well as I rode from the airport to the DT core in Calgary I counted. 4 out of 5 . Must have been a good day. Understand I didn't venture outside of DT other than along Macleod trail and the velodrome. Of all the cities I've been to, Calgary has the most fixies by far.
Vancouver Metro is just full of old $hitty craigslist nishikis and apollos. Once in a while you'll see something with a skinny tire. No "scene" if you'd call it that. Right DT even the messengers don't usually ride fixed like they do in Calgary. Vancouver is a fat tire city.
Minor exception is the few that hang around the fixedvan site.
