I agree with you Skip with one exception. Model Railroading is another love of mine and I have built a couple of award winning modules for the club I belong to. Aside from the others in the hobby I find people generally give me the same confused look I get when I show them model cars, planes, or even ships that I have built. Unless one is into a hobby like ours I don't think people understand the work and effort we put into our builds. Most associate the hobby to when they were a kid and build models in a couple of hours. That would be like saying to a true artist "I used to paint pictures when I was in grade 2".
The model is our canvas.
Oh, and by the way I am not a grandpa yet. lol
