City bikes

City legs  and city birds, lead me today to "city bikes". 
Somehow, in student town Leuven (Louvain), bikes sometimes just happen to end up in the river Dijle. 
I have always known about it but was never able to actually see or photograph the phenomenon until this year because of exceptionally low tide, a consequence of riverbank works.
They must be either stolen bikes, thrown in the river after a short ride by the thief, or the result of student activity... students who might or who might not have had a bit too much Belgian beer.
The environment organization cleans up the river in Leuven twice a year and on the average they come up with 300-500 bikes.
