…when you’re trying to shoot a timelapse of Nicolaus Copernicus monument in Toruń. The time seems to be perfect – it’s sunset, weather is fine, your gear is all set, you start shooting and… The Critical Mass participants appear at the monument. There are about 400 of them, with their bicycles. And all they want is to finish the Saturday event right there. Wanna go for a ride, Copernicus?
