I've always questioned this form of building a layout. if i understand it correctly, you are basicly takeing a 4x8 sheet of plywood, and cutting out the shapes od the right of way and attaching it to a frame, as opposed to a table you attach tracks to. Maybe i'm not grasping the idea fully? it looks like a great way to build a layout, especialy when you want to go down under the tracks, but it has my confused. how does it work? my main concern is buying plywood to be cookie cut, and haveing all these scraps that can't be used for anything. i try to use as much as my supplies as possible.
