Thanks for all the great comments guys, I really appreciate it.
I have been busy adding a forest canopy to the bluff behind my curved stone arch bridge. I want it to look like the bluffs along the Mississippi River near Savanna, IL by Palisades State Park. I stopped to count the trees that I have made and installed and it is 495 so far. These are mostly tree tops with the ready-made trees at the base.
I have had it with trees for a few days, so I started building an Atlas Suburban Station kit. I am painting it Milwaukee Road two-tone gray and will use it for my Savanna station. I had my wife help me select the paints at Home Depot by looking at a picture of a real station on my cell phone. After painting the station parts, I love the dark gray, but the light gray is too light. So I rubbed the walls with some medium gray chalk and it looks pretty good to me. It also gave it a moderately aged and highlighted the details look which I wanted.
I will post pictures of my tree canopy and hopefully my new station soon. It doesn't look like I am going to have much time to work on it over the weekend.
