Bike. In the trees?

FietsWith your bike in the trees?

Sometimes we see strange bikes on the road.

So a few days ago, we found this three bikes parked in a tree.
We could not figure out why?
Because of the tour the france? Or because of the dutch cycling week in Drenthe?

They are parked in a small town called Westenbork.

And we thought it is funny enough to show it to our readers.
