I snapped this photo on my way to school today. This is 8:30am rush hour on a normal Thursday morning in Montreal.
I count 19 people on bikes, 13 on Bixi (I think), 4 wearing helmets. I'm not sure even Portland's rush hour can top this.
Also, this photo is of the temporary bike path which was just implemented on President Kennedy, since the normal path on de Maisonneuve is closed for summer festivals.
