I applied a layer of "ground goop". I was able to get a lot closer to the turnout's throwbars with the ground goop. While the goop was still wet, I covered it with a variety of fine ground foam by Woodland Scenics and some dirt (unknown manufacturer). This photo shows what the undeveloped land looks like. Down the road as I get an itch to do some scenery work, I may glue down some bushes, and maybe some trees. The plan is to completely remove a section of scenery whenever I am working on a structure that is supposed to go in a particular area. If I need access to the wiring or a Tortoise, I'll just remove the scenery; it is relatively cheap and only takes a few hours to replace. However, in the meantime I have a somewhat finished-looking layout.
This is the view on the right-hand side of the layout.
And here is an overall view of the layout (as much as I can get into the view of the camera). It gives the impression of a "finished" layout, although much work remains.
