Whilst cycling near Buch, close to the Brandenburg/Berlin border, I came across a white-painted bicycle chained to a tree next to a road-side cross.
It was put there by the ADFC (Allgemeiner Deutscher Fahrrad-Club e.V. - German Cyclists' Federation) to commemorate the death of 21 year old Stefan Meske, a cyclist who was killed here on 24th September 2012.
This is one of fifteen weiße Fahrräder memorials around Berlin to victims of careless road-traffic in 2012.
A sobering thought, as the large lorries speed past.
