Most of us don't have as much model RR real estate as we would like. What do you all think of extending rocky scenery all the way to the floor, then finishing the access isles to look like water -- river, lake, inlet, etc. -- and creating an interesting shoreline. Could even have a perimeter track running special trains along the shore, within reach of the kids... This could result in some dramatic terrain, like John Allen made many years ago. Any of you done anything like this?
