What a beautiful thread, I had the privilege of seeing this fantastic layout in person. It is one of the most beautiful layout's I've ever seen, not to mention it's quite large.
We are so lucky to have Marty and Dotty in this great hobby with us, Thanks Al for this wonderful tour or Marty's layout. Like Marty said above, if you ever are in his area this is a layout that is a must see. Not only will you see a beautiful layout, you will enjoy Marty and Dotty's hospitality and get the chance to see Ralph the cat.
Thanks,
Alex
