I wanted to build a layout for me and my kids to enjoy without the hassles of buying all the power tools necessary to make and build risers. Woodland Scenics has made it a very simple process to build and assemble the Grand Valley Layout Kit. What you do with it along the way is up to you. As you can see by some of my pictures, I've added so much detail to the layout the response on youtube from other model railroaders has been extraordinary. I have not received any negative criticism and some cannot believe that it was a kit.
