Saw the layout set up at the Asheville Train Show for the past three seasons and it just keeps getting better and better. This fella Ty Brown is literally 'a one man show' with help from his wife and the layout is spectacular!
Look closely at the little detains and especially at the grasses, flowers, and scenery in general. If you have a chance to catch it somewhere, make the effort. I believe he's based NE of Charlotte NC and may have a website (hadn't checked) but I think he told me he makes and markets large trees for layouts.
Suggest you click on one of the thumbnails at the bottom and view these full sized.
Do you see the turtle?
