Reply to "What basic scenery products are essential to have on hand?"

I think this layout looks fine. My 5x8 layout is 12 years old. It's base is indoor carpet in a muted green. After a few years of adding stuff, you can hardly see any carpet, as the buildings and scenics rest on it as separate "modules". My only advice is to exchange large "space takers" (like the MTH firehouse) with smaller stuff (like a used car lot and diner). I have no desire for a bigger layout...however, I also have a Christmas layout as well as a small American Flyer postwar layout.
