I really like the beautiful light when dark clouds are forming on the sky and the sun is still shining. In this situation the light from the sun is always magical and I like how pictures turn out when they are taken in this light situation. But it is adivisable to stay close to the car or some other "shelter" so you can get in a dry place if a sudden rainshower starts.
I like how the shadows of trees are forming on the ground from the sun that already stands low on the horizon.
