There is no such thing as the unhampered artist. I know, I've been there.....hundreds of times!
Just when you think the light is perfect, the viewpoint solves most of your compositional problems and you're ready for the final 5 strokes.........the biggest, yellowest school bus comes and parks right in front of your easel!
I did have a memorable experience here though. Earlier in the day, I was about 2/3 finished with the painting when I became aware of someone standing behind me. A very polite voice said, "Your colors are so beautiful! May I take a photo of you and your work?" I thought I recognized her, asked her if her name was Ann and realized we had met the year before while I was painting "Down Holbrook". Ann is a poet who lives on Whidbey Island. I told her I needed help with a title and she came up with a great one: "Going for Green." I'll post a better photo of this painting for you later.
