So let me just post a few photos with a brief explanation. My dad is very interested in visual detail, something he's still capable of as words and concepts and memories of past and present increasingly elude him. Before the strokes and Ruth's death, he used to build extremely detailed Model railroading layouts in N-scale, the smallest of the commonly available sizes for such things. I'm told that he used to paint even the faces of tiny people inside the N-scale school buses and the like!
So today, when I realized that the Gadsden-Pacific Toy Train Operating Museum reopened today after bring closed all summer, I took him down there for a very enjoyable 45 minutes or so. I just wish there was a way to get him involved in working on such things again, instead of just looking at them. But I suppose that's asking far too much if him at this point.
