On my first trip to the US we were on our way to specific location where there is a certain subject given.
As we drove to the spot the fog and the backlight were so beautiful and magical that I stopped immediately and tried to find a certain subject for that specific mood. I found this impressive longhorn and some cows. The flock of birds balances these subjects very well.
From that moment on I always stop at places where the light is special and then try to find a subject instead the other way around.
