This bucolic scene was photographed on my recent trip to Minnesota. The farms there are so beautiful and many look like a painting waiting to happen. I wanted to do an abstracted foreground - 2/3 of the painting, actually - using a palette knife with lots of paint. The texture you get with a knife cannot be obtained in any other way. I also wanted a painting with lots of different shades of green. I think the painting is successful in those objectives.
