I've featured Don before, he's a true to the bone sketchbook artist! I love his photos that include the subject he has drawn. There's just so many things I admire about this type of sketching. I also really love when he incorporates written observations or descriptions with his drawings. Walt Stanchfield states in his wonderful book "Drawn to Life" that your sketchbook should replace your camera, and I think Don is a good example of precisely this happening. Enjoy.
