Yes, I usually seek a quiet location to sketch. Listening to the buzz of the bees and the whisper of the wind is part of the plein air process.
But looking through my sketchbook today makes me realize that sometimes my subject matter is dictated by a lively conversation that I am "drawn" to. I'm likely to sit near a fun person or an interesting conversation, then find that there's always something lovely to sketch. But the other sketchers - oh, they are the loveliest of all.
Out laundry sketches become a marker in time and place in our little world - kind of like Van Gogh and Gauguin at the yellow house in Arles.
