Neat photo. Without knowing anything about the photo, I would guess that this was probably one of Walt's last times in the park. He looks a lot like he did during the EPCOT film, which he reportedly struggled to get through while in failing health. Perhaps he's not so much deep in thought as he is just trying to catch his breath after walking across Town Square
What a beautiful photograph. Such a great guy, well-beloved and greatly missed. The last half-century has been a dreary time without you, Walt.
