What is your favorite aspect of model railroading?

[secondhandmodeler]

I have to admit that one of my favorite parts of model railroading is thinking about it. When I'm reading or thinking about trains I don't ever think about work or other sources of stress. In terms of actual modeling my favorite part is building scenery. Whether it's natural scenery or buildings and roads, building the scene for the trains is my favorite part. The trains become an actor in the scene so to speak.
