The challenge in Stream Crossings on “Streams in winter” inspires me to dig out a shot from the best hoarfrost day that I ever experienced in my photographic life (I remember some from my youth, but that was long ago and very long before the age of digital photography).
This shot was taken in the most beautiful park of the country-house of Groeneveld near Baarn which you know already from quite a few shots.

Groeneveld, 22nd December 2007, 10.00 am
Nikon D80, Nikkor 18-200 mm at 200 mm
F 10, 1/60, ISO 200

Here two more shots from that great morning in Groeneveld park:

And here a later shot of this bridge from November 2008:
